Medieval packhorse bridge. The structure is the only medieval bridge on the Island, and may date from the 12th century when Rushen Abbey was founded. It leads to the abbey's extensive agricultural estates which were spread through the north and east of the parish of Malew. The bridge is humpbacked, spanning the Silver Burn with two main arches. There is also a small subsidiary opening by the west bank. The bridge is 13m long and just 1.9m wide, with 1m high parapets on both sides. The arches are pointed and constructed of narrow voussoirs set in plenty of lime mortar (similar to the construction of the round vault in the chapter house of Rushen Abbey). The bridge is defended against the flow of the river by sharp cutwaters on the upstream face.

Coin - a single sestertius - of Trajan (A.D. 98-117), found in the masonry of Monk's Bridge, Ballasalla. The coin is in the Manx National Heritage collections, accession no. 1954-2530.

A post-medieval house at the northern edge of Ballasalla.

The site of a 19th century mineral water factory in Castle Street & Brunswick Road, Douglas. It was operational in 1889 and 1894.

The site of a post-medieval bleachfield.

The site of a post-medieval carding mill.

The site of a post-medieval spinning mill.

Worked flints of indeterminate character including a blade, and a possibly utilised stone, found in Ordnance Survey Field no. 1542, Moorhouse farm, Rushen. The precise findspot is not recorded and the grid reference refers to the centre of the field. The artefacts are in the Manx National Heritage collections, accession no. 1989-0061.

Undated enclosure. A circular enclosure is sometimes visible as a cropmark on a slight ridge running through Field no 414683 (Isle of Man Government digital mapping, 2016), centred at the grid reference provided. A small scale test excavation by AM Cubbon (Manx Museum director 1956-84) in the 1970s demonstrated that the cropmark was the result of an artificially created ditch, on the strength of which it was suggested that the enclosure might relate to an Iron Age ringfort of the kind excavated by Dr G Bersu (see PRN 0007, PRN 0008).

A flint scatter of early prehistoric date recorded at Moorhouse Farm.

A mound of uncertain origin and date on Moorhouse Farm.

The site of an early medieval to late medieval burial ground which was excavated by Larch S. Garrard.

Early prehistoric flints were found here by L.S. Garrard during excavations at Moorhouse Farm.

Modern brewery. The Ordnance Survey 1:2500 First Edition mapping of 1868 shows a disused brewery at this site. The brewery was centred at the grid reference provided. The brewery was owned by Edward Gawne, who later acquired Kentraugh, and the family also owned Mount Gawne (now The Mount) which stands just to the north-west of the brewery. Gawne was a lawyer and banker who issued card-money locally. In the 1850s the brewery was being operated by Connal & Co., but by the late 1860s had gone out of use. The site has been subject to substantial redevelopment in the latter 20th century as a motor garage, despite which two of the larger buildings had survived, although altered and reused as dwellings. In 2016 the entire site, including the surviving 19th century structures, were finally cleared and redeveloped for housing.

A substantial circular cropmark, estimated as 90 - 100 feet in diameter, was noted by AM Cubbon in June 1975, and estimated to be centred at the grid reference provided. Isle of Man Government aerial photography (2015) confirms the faint presence of two, not quite concentric circular marks, in the area earlier indicated. The inner mark is the more blurred of the two and measures approximately 40m in diameter. The outer mark is better defined, particularly to the north and west, and appears to be a ring 65m in diameter.

Prehistoric flint scatter. A small quantity of worked prehistoric flint was recovered from Mount Karrin by CH Cowley. It is possible that Cowley was drawn to this locality by the presence of the well-preserved burial mound (PRN 0452). No further details concerning the circumstances of the discovery were recorded and the grid reference relates to the vicinity of the mound for indicative 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.

Undated standing stones. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 records this site, together with the annotation, 'Standing Stones'. The stones could not be found by a Royal Commission field inspection in 1955, and no trace was found when the site was developed for residential purposes in the 1990s.
