Banks Chambered Tomb aka Tomb of the Otters [currently closed] Cleat, South Ronaldsay (KW17 2RW Click for map). This Tomb appears to date from around 3340 BCE and was in use for several centuries. It is unique in Orkney as it was quarried out of solid bedrock. Only one of what looks like six chambers has been excavated (in 2010). Not far from the Tomb of the Eagles, its second name arises from the discovery of otter bones. The land east of Banks (and south of the visitor centre for the Tomb of the Eagles) was explored a year later. This revealed that there were ‘a significant number of prehistoric houses, dykes, fields, terraces etc, and some of these are elements of coherent settlements’ (Canmore). See, also The Megalithic Portal.
The Cairns, Windwick Bay, South Ronaldsay (KW17 2RN click for map). A fascinating site that has been featured on Digging for Britain [series 12, programme 3]. The current work at The Cairns began in 2006. It is exploring a large, with the investigation now focusing on excavating a substantial broch or Atlantic Roundhouse (over 21m in diameter with five different internal areas). See Cairns for more details. There are also other Iron Age and Norse period structures. See, Canmore and The Megalithic Portal. We also feature it in Places to Visit 5. [2025 Dig: This year’s season will start on Monday, June 9, 2025, and run until Friday, July 18. There will be at least one dig open day. It is scheduled for Friday, July 4.]
Harra Brough, Broch or Nuraghe – Herston, South Ronaldsay (KW17 2RH click for map. There is some doubt about whether this is a Broch as the site is inaccessible and the approach is difficult and dangerous. However, viewed from the clifftop the site is fascinating. The Megalithic Portal describes it as follows: ‘A rather mysterious site… located on an extraordinary coastal outcrop named The Altar on the OS map’ The Portal also has an excellent picture of The Alter [see, also, Canmore]
Howe of Hoxa, Howe, South Ronaldsay (KW17 2TW – click for map). Situated on a hill that looks out across Scapa Flow to the Orkney mainland and to Flotta and beyond, this Iron Age circular broch also affords views across fields to the nearby Sands of Wright and Widewall Bay. It can be accessed from the track to Howe. A path to the left of the house takes you to the site. Unfortunately, the broch looks to have been altered soon after it was first ‘dug’ in 1848. It has an internal measurement of just over 9m and there appears to have been a stairway to the upper floors. As we note elsewhere in these pages, Thorfinn Torf-Einarsson aka Thorfinn Skull-splitter (who appears in the Orkneyinga saga) is said to be buried here in around 963. [See The Megalithic Portal and Canmore].
Isbister Chambered Tomb aka Tomb of the Eagles [currently closed]. When open entry is via the Tomb of the Eagles Visitor’s Centre, Cleat, South Ronaldsay (KW17 2RW Click for map). This Neolithic chambered burial tomb is over 5000 years old. Sadly, it is likely to be shut for some time. The South Ronaldsay and Burray Development Trust is raising funds to take on the running of the tomb (see Crowdfunder). It is located on cliffs not far from Isbister Farm (Canmore and The Megalithic Portal)
Liddle Burnt Mound, Isbister, South Ronaldsay (KW17 2RW, click for map). Liddle is said to be the best example of a burnt mound in Orkney, and given that there are around 200 of them, it is significant. From material gathered from the site it looks like the building was in use from around 1200 to 500 BCE. Given the design of the building, the artifacts and burnt bones, and the prominent tank and hearth, it seems to indicate that it was used for cooking. The building was oval and measured around 6.5m x 4m. [See Canmore, The Megalithic Portal and Wikipedia]

Little Howe of Hoxa, Howe, South Ronaldsay (KW17 2TW – click for map). The Little Howe of Hoxa can be accessed by track/path from the track to Howe (described in Five Places to Visit – visit 4). It was a settlement – the ruins of which are now largely covered by grass. Some structures remain but are said to be prone to collapse. [See The Megalithic Portal and Canmore]
The Wart, Hoxa Hill, South Ronaldsay (KW17 2TL, click for map). Close to the summit of Hoxa Hill and south east of an observatory, we find The Wart – a chambered cairn. Canmore describe it as a ’round cairn of Orkney-Cromarty type, probably with a tripartite chamber’. You can reach the cairn by walking up the track to the right of Roeberry House on the B9043 (click for map). Great views from the top. [See The Megalithic Portal]
