Chibbyr Pherick, also recorded as Chibber Noo Pherick (St Patrick's Well), Chibber Sheeant (Holy Well) and Chibber yn Argid (Well of the Silver), is a spring on the seaward side of Peel Hill below Corrin's Tower. According to Manx folklore, the well sprang forth when St Patrick's horse stumbled and dislodged the ground during his travels across the Island. It was long regarded as a holy spring whose water was sought by the dying as a form of comfort and blessing, though it is now in poor condition.

Chicken Rock (Manx: Carrick ny Kirkey) is a low, largely submerged reef 4.5 km south-west of Spanish Head, marking the southernmost point administered by the Isle of Man. According to a contemporary account reproduced in later retellings, at least 70 shipwrecks and 160 deaths occurred on the island's southern shores between 1822 and 1867 (this specific figure could not be independently confirmed against the Northern Lighthouse Board's own records or Manx Notebook, and should be treated as an unverified period claim rather than an established statistic); in response, the Northern Lighthouse Board's engineers David and Thomas Stevenson built a 44-metre tower directly on the rock, with the final stone laid 6 June 1873 and the light first shown on 1 January 1875, replacing two earlier leading lights on the nearby Calf of Man. The rock is exposed above water for only about five hours a day, making its construction one of the most hazardous lighthouse-building projects of the Victorian era.

Chicken Rock Lighthouse stands on a treacherous reef off the southern tip of the Calf of Man, built after mariners found that fog often obscured the Calf's older lights, making the reef a serious hazard to shipping. Designed by the engineers David and Thomas Stevenson, the 44-metre granite tower was under construction from 1868 to December 1874, cost more than £64,000, and was first lit on 1 January 1875. A serious fire on 23 December 1960 badly damaged its interior and injured one of the three resident keepers, all of whom were rescued by the Port St Mary lifeboat; the light was automated the following year and has been unmanned ever since. It remains an active aid to navigation operated by the Northern Lighthouse Board, flashing white every five seconds with a range of around 18–21 nautical miles, though the tower itself is not open to visitors.

Christ Church stands on Church Hill in Laxey and was built for, and largely funded by, the Great Laxey Mining Company at a cost of around £950, reflecting the mining company's central role in shaping the village during its Victorian boom years. It was designed by the architect Ewan Christian and was consecrated on 27 May 1856 by the Bishop of Sodor and Man, Lord Auckland. The church remains a prominent landmark on the hillside above the village that grew up around the Laxey mines.

Church Bends is one of the longer-established named corners on the Billown Circuit, with a racing history stretching back decades. Wikipedia's article on the circuit records three fatal accidents there: Jim Farlow in 1974, Graham Williams in 1983, and John Tawse in 1985, making it one of the course's more consequential sections through the 1970s and 1980s.

No verifiable history was found for this building beyond its identification as Church Cottage in the St Marks village settlement, Ballasalla, close to St Mark's Church.

Church View House stands on Main Road, Kirk Michael, and is registered as a house. No further verifiable history specific to this property could be found online.

St John's Church, on Main Road, is the Royal Chapel of St John the Baptist, from which the village of St John's takes its name, standing immediately beside Tynwald Hill. It serves as the Island's national civic church: each Tynwald Day, 5 July, a religious service is held in the chapel at 11 o'clock as the opening act of the day's ceremonies, before proceedings move outdoors to Tynwald Hill for the promulgation of the year's laws in English and Manx. Inside, reserved seats bearing name plaques are set aside for members of both branches of Tynwald, the Manx parliament, reflecting the church's continuing role in the Island's system of government alongside its ordinary parish duties.

Cleveland is a city in north-east Ohio, United States, known as the Manx Capital of America. From the 1820s onwards, large numbers of Manx emigrants settled in the Cleveland area and the surrounding Western Reserve, with the population of Manx origin estimated at 25,000 to 30,000 by the mid-twentieth century. It is the headquarters of the North American Manx Association, founded there in 1928. The settlement can be dated closely. The first Manx pioneers reached the Cleveland district in 1826: three families, William and Eleanor Kelly, Patrick and Ann Tear, and William and Mary Kneen, with seven children between them. In 1827 something like seventy families, about two hundred people, followed into Ohio, among them Thomas Kelly of Doolough Farm in Jurby, who left on 6 July with his father, sister, wife and five daughters, and whose diary is the fullest of those that survive. The names that took root were a roll of the Island: Crellin, Shimmin, Kaighin, Cowley, Collister, Gelling, Kermeen, Monier, Mylchreest, Carran, Kewley, Lewin, Bridson, Crow, Killip, Cain, Corkill, Looney, Clucas and Kneen. They organised early and stayed distinct. A Manx Society was founded in the city in 1851 by James Christian, John Corlett, William K. Corlett, William Cubbon and William Brew, to take care of the immigrant who arrived with an empty pocket or in feeble health, and it holds an honoured place among the pioneer bodies of its kind. The deed for the acre on which the Laxey church was built was signed on 23 June 1855, four of its five trustees bearing Manx names, and it was laid down that whatever society used the building must adhere to the doctrines of the Primitive Methodist Church. The community had the reputation of being a somewhat clannish body of immigrants, and at one association dinner the speaker of the evening told several stories in Manx which the audience understood perfectly. Its people did well. Dr William T. Corlett, grandson of an original immigrant, won an international reputation as a specialist in diseases of the skin. Thomas Quayle, who came out with his parents in 1827 at sixteen, already apprenticed as a ship's carpenter, founded a famous shipbuilding firm in the city. W. Sheldon Kerruish, born in America to parents of the 1827 migration, became outstanding in law and public speaking.

This North Quay building was home to the Lake Brewery, founded in 1779 by George Booth and later taken on by John Williams Clinch III, who rented it from 1863 and owned it by around 1868, trading as Clinch & Co. The firm was known by two Manx Gaelic mottoes, "Glen as Lajer" (Clean and Strong) and "Three Fists," and Clinch remained managing director until his death in 1905, having earlier been forced to float the business under pressure from its bankers in the 1890s. The brewery traded on into the twentieth century before being absorbed by the Castletown Brewery in 1945 and closing the following year; the surviving quayside building today holds offices, shops and a public house, reflecting its old commercial and drinking-house use.

Close Lake House on Jurby Road, Andreas, was registered as a protected building in August 2001. It is described in official records as a mid-Victorian, double-fronted house, though no further published history of its construction or occupants has been found.

This former engine room on Carrs Lane, Tromode, belonged to Clucas' Laundry, a firm that began in a house on Circular Road, Douglas, in 1906 before moving to Tromode in 1912 and becoming a private company in 1922, when it acquired the whole of Tromode Village and Mills; the site had formerly been used for making Moore's sail cloth. Clucas' grew into one of the largest and best-equipped laundries in the United Kingdom, running a substantial brush-making factory alongside it, and was noted as the only laundry company in the British Isles to provide housing for its entire workforce, owning every house in the village its employees lived in. The engine room is a surviving fragment of that industrial operation, now included on the Isle of Man's Registered Buildings list.

The Clypse Course was a 10.79-10.95-mile, 34-turn street circuit through Onchan parish, introduced in 1954 to bring back the Lightweight, Ultra-Lightweight and Sidecar TT races, and used through the 1959 season before those classes returned to the Mountain Course. From the Grandstand it shared Bray Hill, Parkfield Corner and Willaston Corner with the Willaston Circuit, then ran its own loop past Ballacarrooin (the course's high point at 856 ft, OS grid SC 406 827) to rejoin the Mountain Course in reverse at Cronk-ny-Mona, out to Creg-ny-Baa, back down the Onchan-Laxey road to the Manx Arms, up through the Nursery Curves to Signpost Corner, and on to the finish. Carlo Ubbiali and Tarquinio Provini each won four races on the course, MV Agusta won eight of the ten manufacturer's titles contested, and Inge Stoll became the first woman to compete in an Isle of Man TT race here in 1954; Provini set the outright lap record in 1959 at 80.42 mph. No turn-by-turn coordinate list for the course was found in the sources checked; most of its distinctively-named points either duplicate Willaston Circuit or Mountain Course landmarks already covered, or (Ballacarrooin, Nursery Curves, Manx Arms) have no independently sourced coordinate.

Cockermouth is a market town in Cumberland (now Cumbria) in north-west England, at the meeting of the rivers Cocker and Derwent. It was the birthplace of Fletcher Christian, leader of the 1789 mutiny on HMS Bounty, whose family were the Christians of Milntown in the Isle of Man. The Cumberland connection ran both ways for generations. Hutchinson's history of the county is cited by the Manx antiquaries for the Christians having been established in the Isle of Man as early as 1422, having previously been settled in Wigtownshire, so the family moved between the three coasts of the Irish Sea. Other Cumberland families married into the Manx gentry in the same period. John Senhouse, High Sheriff of the county, died in 1767 and was succeeded by his son John, who in 1775 married Margaret, daughter of John Taubman of Castletown. Mary, daughter of John and Bridget Senhouse, married Edward Law, Bishop of Carlisle, and among their children was the son who became Lord Chief Justice as Lord Ellenborough, whose opinion was relied on in the settlement of the Duke of Atholl's Manx claims.

This level gate hut at Colby once housed the crossing keeper who operated the manually worked gates where the Isle of Man Railway crosses a local road. No further verifiable detail about the specific structure could be found online beyond its register listing as a level gate crossing.

Compton House stands on Castle Street with its notable shop-front, red sandstone steps, fanlight doorcase and cobbled paving in front. William Henry Cooper's account of the town dates the building to probably the early 19th century, though its architect is unrecorded, and describes it as originally housing a milliner and tailor's business run by George Bradshaw; Brown's 1894 Directory likewise lists a Mrs Mary Rebecca Bradshaw, general draper, trading as Compton House. The building later held the Bon Vivant restaurant in its cellar and has more recently been used as offices, including by an estate agency.

Conquet is a port town on the western tip of Brittany, France. Its inclusion in a Manx heritage context relates to the maritime connections between the Isle of Man and the French Atlantic coast, particularly during the period of conflict and trade in the eighteenth century.

Corrin's Tower stands on Corrin's Hill above Patrick, on the west side of the Island overlooking Peel. It was built in 1806 by Thomas Corrin, a local landowner remembered as an eccentric figure, who raised the pillar, tower and mount as a memorial to his wife Alice Corrin and their two children, whose remains were laid beneath it. A later inscription on the pillar, dated 1850, records that it was erected "six feet distant from the base of this mount," so that the family's remains would rest undisturbed "until reanimated by the power of God." The tower is one of several early nineteenth-century hilltop memorials on the Island and remains a distinctive landmark visible from Peel and the surrounding coast.

Cosy Nook is a row of vernacular cottages on Shore Road at the western end of Port Erin beach, long used as a café and a familiar landmark on the seafront. The building now houses Kishtey Çheh, a beach spa. Beyond its location and current use, detailed construction history for the building was not found.

Cott-ny-Greiney on Beach Road, Port St Mary, is registered as a traditionally thatched Manx cottage, a rare surviving example of the island's older vernacular building style close to the shore. No further verifiable history beyond this listing description could be found online.

Cottage Grove Lake is a locality in Ohio associated with early Manx settlement in the Western Reserve region. Manx emigrants began arriving in north-east Ohio from the 1820s, establishing farming communities across the area that maintained close ties with the Island and with the larger Manx community in nearby Cleveland.

Ramsey's old Court House and police station on Parliament Street once served as the town's judicial building; it has since been repurposed and is now used as a community and town-centre event space. It is registered on the Isle of Man's Registered Buildings list as a public building. No further verifiable detail on its construction date or architect was found online.

Cranstal Cottage, on the coast road between Bride and the Point of Ayre, is a thatched traditional Manx cottage that was among the very first buildings placed on the Isle of Man's protected buildings register, in May 1983. It stands close to a matching thatched neighbour, Bridge Cottage, and the pair are among the best-known surviving examples of the island's vernacular thatched cottages in this exposed northern corner of the island.

Creg Willey's Hill is the name given to the steep climb that begins after the right-hand turn at Sarah's Cottage and continues up to Lambfell, even though the hill technically starts back at Glen Helen. It is essentially a topographic name for this stretch of climb rather than the site of a recorded incident.

Manx: "rock of the cow".
