Modern chapel. The original Primitive Methodist chapel at Dandy Hill in Port Erin was replaced by an enlarged structure on the same site in 1860. Edward Gawne of Kentraugh and William Milner and his family contributed towards the cost of the building and additional land. The chapel served until 1903 when a larger chapel opened in Station Road, but continued in use as a Sunday school until 1963. It has since been demolished and the site redeveloped.

Modern chapel. The original Wesleyan chapel at Victoria Square in Port Erin was opened in 1881. It was replaced thirty years later by a new and larger chapel on land adjacent, and converted to use as a Sunday school. The building is now used as a workshop.

Modern chapel. The original Wesleyan chapel at Victoria Square in Port Erin was replaced in 1911 by a new and larger chapel on land to the east. The chapel closed in the early 1970s, and the spire was demolished as unsafe in 1983. The building has since been converted into an arts centre and has been extended several times.

Prehistoric flint scatter. A single worked prehistoric flint was recovered from Port Grenaugh by CH Cowley. The findspot cannot be re-identified from the description and the grid reference is provided for reference purposes only. The antiquary Charles Harry Cowley was an avid collector of worked flint and coarse stone artefacts revealed by agricultural activity, mainly on farms located around Peel, and occasionally from further afield. He was active from 1900 until 1943. His entire collection of artefacts, together with a daybook cataloguing his discoveries, was later donated to Manx National Heritage.

The reported site of an early medieval cemetery where lintel graves have been found.

Iron Age defended promontory. This headland stands higher than the adjacent land, a natural defence which is augmented by a bank and ditch protecting the interior of the promontory. The bank still rises 2.5m from the bottom of the ditch, despite the former no doubt being eroded and the latter partially filled with debris. The inner height of the bank is 1.3m. The whole site is covered by vegetation and the interior of the promontory shows no trace of internal structures, nor of a peripheral bank. The site lies just 250m from the defended promontory of Cronk ny Merriu (1068).

The reported site of a possible Bronze Age burial cist.

The site of a series of possible "pit dwellings", represented by circular depressions cut into the rock.  They were described as being located on a rock, almost perpendicular on all sides, the western edge of which was protected by an embankment. It was recorded that 'Inside the embankment is a circular depression about 8 foot diameter, the earthen walls being about 2 foot or more in height.'  Similar depressions were seen to the northeast and southeast of the most obvious depression. Later inspection noted four approximately circular depressions on top of the rock, with average diameters of 5.0 metres and average depths of 0.3 metres. From the cliffs above they appeared to be hut circles but close inspection revealed that they had been created by subsidence caused when the rock mass broke away from the cliff. Evidence of this subsidence can be seen around the rims of the depressions. No evidence of a protecting embankment was found.

Modern church. St Mary's Church, Port St Mary, was completed in 1884, on land given by Mrs Emily Gawne (1814-1889, great grand-daughter of John Murray, 3rd Duke of Atholl and Lord of Man). Mrs Gawne was a generous benefactor of the poor and contributed to educational and religious good causes throughout the parish of Rushen.

First World War and Second World War. There are two upright monuments in polished black marble, both inscribed with the heading "We will remember them / Cooineemayd orroo" followed by a list of the names of the fallen; their regiment and the war in which they served.

Modern gas works. The gas works was constructed in the 1890s, and was the last site on the Island to produce gas from coal, ceasing operation in 1971. The site was subsequently converted to supply natural gas. The gas storage tanks are now redundant and redevelopment is now in prospect (2016).

Port St Mary harbour has the advantage of some natural shelter from the prevailing wind. This has been enhanced by two main piers, of cut limestone. Cannon bollards are reputed to have been lifted from off the Chasms by the Laird of Melgin in 1664 but old iron guns were similarly re-used at Douglas and, as may be seen from an illustration, at Ramsey. As usual, the ends of the breakwaters are marked by lights. The lifeboat was established in 1896. Although it has a boathouse, it normally lies at anchor because the harbour dries out at low tide. Nevertheless this is a popular centre for small craft.

Modern horsewalk. The Ordnance Survey First Edition 1:2500 map of 1868 shows a horsewalk at this location.

The inner pier at Port St Mary was completed in 1812; it is one of the oldest surviving harbour structures on the Island. The dogleg structure extends out a total of 225m to the Bealevayer Rock, protecting the harbour from the south-east and east.  Its end is marked by a lighthouse (3898.00). The inner harbour, which is tidal, was improved by the creation of the new west quay in 1848 and the port's facilities were later significantly enlarged by the completion of the outer breakwater in 1886 (further extended in 1892), creating the outer harbour which is accessible at all states of the tide.

Modern lighthouse. The Ordnance Survey First Edition 1:2500 map of 1868 shows a lighthouse at this location on the end of the old breakwater on the Bealavayer Rock.

First World War. Brass plaque, oak surround. Unveiled November 1922 by Major General L.C. Dunsterville, C.B., C.S.I, J.P.

Modern limekiln. The Ordnance Survey First Edition 1:2500 map of 1868 shows a limekiln at this location. It is possible that this kiln is the one illustrated on a landscape painting by John 'Warwick' Smith produced in 1795 (one of a series of accurate landscapes of the Isle of Man produced by Smith for the Duke of Atholl).

Modern chapel. The original Primitive Methodist chapel in Port St Mary stood on the corner of Lime Street and Loch Road, until replaced by Mount Tabor in 1903. The gable faced Lime Street whilst the entrance porch was on the south side facing Loch Road. The building was subsequently altered by the insertion of a wide vehicular door in the east gable and used as a coal store. It has since been demolished and replaced by modern garages, and the adjacent road junction widened.

Modern chapel. The Mount Tabor Primitive Methodist chapel opened in 1903 and replaced the original Port St Mary chapel which stood on the corner of Lime Street and Loch Road. The replacement chapel is much larger than its predecessor and incorporates a Sunday school and other ancillary rooms. It was built to the designs of Todd & Morris of Southport.

The Ordnance Survey 1:2500 First edition map of 1867 shows a Primitive Methodist chapel to the south of the harbour. The chapel was closed during the second half of the 20th century, though it continued in use as a Sunday school until 1975. The building was sold in 1980 and converted for alternative use.

Modern smithy. The Ordnance Survey First Edition 1:2500 map of 1868 shows a smithy at this location. The much altered building is now used as a storeroom.
