Modern lifeboat station. Former lifeboat station comprising lifeboat house and slipway. The lifeboat station was built in 1896 in order to accomodate a new and larger lifeboat serving the area. At the same time a new slipway leading directly down into the outer harbour was constructed, replacing the older slipway which ran against the harbour wall. The facility was in use until 1922, when the station closed and responsibility for the southern coast of the Isle of Man was transferred to the Port St Mary station. The boathouse was subsequently used as a garage for motor coaches before being converted into offices for a containerised shipping company. It was later converted into a private dwelling. It is now a Registered Building, No 60, and was placed on the register on 24th February 1984.

Modern boatslip. Former lifeboat slipway. The lifeboat station and slipway were built in 1896 in order to accomodate a new and larger lifeboat serving the area. The new slipway, descending straight from the quayside opposite the doorway of the boathouse, into the outer harbour, replaced the older slipway which ran against the harbour wall. The facility was in use until 1922, when the station closed and responsibility for the southern coast of the Isle of Man was transferred to the Port St Mary station. The slipway is now used for general harbour purposes.

Modern RNLI boathouse. Former RNLI boathouse, built in 1896 in order to accommodate RNLB Thomas Black, a new and larger lifeboat serving the area. The boathouse was in use until 1922, when the station closed, the 'Thomas Black' was decommissioned, and responsibility for the southern coast of the Isle of Man was transferred to the Port St Mary station. The boathouse was subsequently used as a garage for motor coaches before being converted into offices for a containerised shipping company. It was later converted into a private dwelling. It is now a Registered Building, No 60, and was placed on the register on 24th February 1984.

A lighthouse at the entrance to Castletown Harbour, built in 1849 by James Gelling.

A lighthouse recorded at the entrance to Castletown Harbour.

A 19th century lime kiln recorded at Castletown.

Modern chapel. The original Wesleyan Methodist chapel on this site was constructed around 1801. It was superceded by a larger chapel in 1834, and the old building leased out until 1867, whereupon it became the Sunday school. It still serves as the church hall today for Castletown Methodist Church. Both structures are gable end on to Arbory Street but are stepped back from the building line of the houses to either side. Both buildings have been the subject of piecemeal additions. The later chapel in particular was enlarged by the provision of a substantial apsidal extension on the southerly gable lit by three windows.

Modern chapel. The original Wesleyan Methodist chapel on this site was constructed around 1801. It was superceded by a larger chapel in 1834, and the old building leased out to a corn merchant until 1867, whereupon it became the Sunday school. It still serves as the church hall today for Castletown Methodist Church. The building is gable end on to Arbory Street but are stepped back from the building line of the houses to either side. Comparison with the original Ordnance Survey 1:2500 mapping of 1868 shows that the southern end of the building has been extended by about 4m.

Modern chapel. The second Wesleyan Methodist chapel on this site was completed in 1834. From 1867 it was served by a Sunday school located in the former chapel to the east, which during the intervening decades had been leased to a corn merchant. The chapel is gable end on to Arbory Street but is stepped back from the building line of the houses to either side. It was enlarged at some point after 1868 by the provision of a substantial apsidal extension on the southerly gable lit by three windows, and by smaller single-storey extensions to either side.

Modern church. The Primitive Methodist chapel in Castletown was completed in 1893. It is an imposing structure, and is believed to be to the design of Thomas Howdill of Leeds. The chapel was closed in 1972 when the Methodist congregations merged, and for a time was used as a furniture warehouse. It was later converted to offices and is still used as such.

This single storey stone building has a pitched slate roof and abutts adjacent structures on either side of the corner between Castle Street and The Quay. The corner itself is marked by a circular turret with a conical roof and a band of vertically proportioned rectangular windows which repeat elsewhere on the two facades. There is an entrance on each street indicated by a single door with semi-circular headed opening in the stonework. There are also two curved gable extensions which cut the eaves line, sandwiching the chimney to the corner turret from The Quay, and marking the junction with the adjacent building on Castle Street. The general character of the architecture, though at pains to complement Castle Rushen on the opposite side of the road, gives a general air of discomfort in its expression in which the turret seems somewhat contrived. No interior inspection has been performed. The building appears to be in good repair. Because the architect was Baillie Scott there is a tendancy to list the building for that reason alone. However its architectural curiosity value may carry as much weight even though some of it's aspects could be considered dubious. The marriage of 'castle expression' in such a small building gives an impression that the design is overworked. Whereas such numerous elements have been successfully integrated in some of the large Douglas houses of the Arts and Craft Movement style they do not appear to lend themselves as readily to a police station solution. However in balance it is suggested to list the building for preservation as an example of the architect out of his normal context. The above description was prepared before the creation of Registered Building and Conservation Area legislation for the Island and represents a provisional assessment in support of its protection. The structure is now owned by the Manx Museum and National Trust, and is inscribed in the Protected Buildings Register (No. 27).

Below are three columns of names, 65 in total. First World War. Hand-written scroll in a fretwork frame. Moved to join with Wesleyan chapel in 1972.

A late 19th century railway bridge at Castletown.

Modern railway bridge. The railway bridge was constructed to carry the southern branch of the Isle of Man Railway from Douglas over the Silver Burn and on towards its terminus at Port Erin. The line opened in 1874. The stone-built, arched bridge spans the river and an adjacent track.

The late 19th century railway station at the northern edge of Castletown. The station building is believed to date from just after the formal opening of the Douglas to Port Erin line in 1874.  It is the only original stone station building to survive on the route, and is furthermore distinctive because of the use of the local limestone. The structure was inscribed in the Protected Buildings Register in 2008 (No. 257), together with the neighbouring goods shed, which dates from 1901, and replaced an earlier timber structure of 1881 which had become too small for the volume of business it was required to handle.

The site of a post-medieval rope works in Castletown.

A large wooden frame, containing portrait photographs of military personnel from Castletown who served in the First World War. It was created by the Castletown Branch Royal British Legion after the First World War. The top of the frame is decorated with three emblems: one of an anchor, one of the three legs of man and one of the flag of St George.

The roll of honour was originally located on a wall adjacent to the entrance to Castle Rushen. It was erected in December 1916 when the war was still ongoing. At a later date it was moved to the Royal British Legion Hall, Janet's Corner, Castletown, where it is currently on display. It contains one column for Navy servicemen and six columns for the Army. There are a further six columns listed at the base of the roll, with the words "Supreme Sacrifice". Not all names are listed alphabetically, as some names were added at a later date. At the time of unveiling it contained the names of 316 men who were serving and 18 of those who had fallen. Paper mounted in wooden frame. The roll of honour was designed by Mr J.E. Teare, architect, Athol Street, Douglas, who also penned the decoration and the list of names. The wooden frame was constructed by Messrs James Cooper and Sons, Castletown.

A sundial consisting of an eighteen sided stone block, which has sixteen faces for use as sundials through the insertion of metal plates. The block is mounted on an heavy circular column with spardash finish and without decoration except at the head - where a saw-tooth moulding rings the column immediately below a small plain cornice. The block itself is surmounted by a tapered curved column supporting a stone ball. The monument is sited prominently in front of the castle on Market Square.

Tiered stone plinth with a Celtic stone cross mounted on top. To the rear of the memorial are three wall-mounted tablets. First and Second World War. Left-hand tablet contains 39 names '1914-1918 in memory of'. Middle tablet contains list of 36 names '1939-1945 in memory of'. Right-hand tablet contains list of 39 names '1914-1918 in memory of'. Names are generally listed alphabetically with a few exceptions. Memorial and names from First World War tablets unveiled on 2 August 1923 by the Lieutenant Governor and dedicated by the Bishop. Memorial designed by Messrs J. Corrin and Son, and a proportion of the work was carried out by the two local firms of Mr C. Cubbon and Mr S. Killey, monumental masons. The stone is from W. Kissack's limestone quarry, Scarlett. (Mona's Herald, 8 August 1923, p.7). Tablet bearing the names of the fallen in the Second World War was unveiled on Remembrance Sunday, November 1949. (Mona's Herald, 15 Nov 1949, p. 2).

Below are two alphabetical lists of names, one of 10 for those that fell and one of 93 for those men from the church that served. First World War. Roll of Honour consisting of wall-mounted plaque. Paper inside wooden frame.

A post-medieval house in Castletown.

Medieval chapel, burial ground, lintel graves, hollowed stone, and possible holy well. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 shows the site of a chapel and burial ground at this location, together with the annotation, 'Chapel & Burial Ground (Site of)'. A marker is placed on the site, which lies in an open field a little to the north of a field boundary. The OS particulars state 'In the field situated immediately NE of the house is pointed out the site of an ancient Chapel and Burial Ground. A few years ago several Kist-vaens containing human remains were discovered.' Authorities quoted: Mr Clucas, Strang; Mr Kelly, Castleward; Oswald's Vestigia'. The Manx Archaeological Survey (1918) recorded that the then owner never recalled seeing any graves at the site during the 40 years that he had lived there, despite the field being frequently ploughed. The same owner reported the presence of a nearby well and had found a hollowed stone, supposed to have been a font, in the hedge close to the site. He had no knowledge of a dedication for the chapel, nor a name for the well.

Medieval chapel. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 shows the site of a chapel and burial ground at this location, together with the annotation, 'Chapel & Burial Ground (Site of)'. A marker is placed on the site, which lies in an open field a little to the north of a field boundary. No direct evidence for a chapel has been found at the site. The discovery of an artificially hollowed stone, which may be a font, does however suggest that a building may have been present on the site. Furthermore, the regular form of the surrounding field pattern would imply that the farm was the subject of the type of rearrangement and improvement which saw the introduction of new efficient agricultural practices in the 1830s and 1840s. This may have resulted in the clearance of the site and the incorporation of materials from a chapel structure into a new hedge nearby, and would also appear to be consistent with the discovery a few years before the OS of several lintel graves at the site.
