A rare lowland broch preserves a six-metre-thick wall, entrance controls, an internal stair and a much older cup-and-ring-marked stone set into its fabric.

Architecture, archaeology and continuing use
The roughly circular drystone structure measures about 23 by 20 metres and has a wall around six metres thick. A south-eastern entrance retains door checks and a bar-hole, while a wall passage and stair led upward. Three outer ramparts once strengthened the approach.
Its story
Later-prehistoric builders chose the high edge of a sandstone cliff in Tor Wood for a substantial roundhouse. They incorporated a carved stone already ancient in their time. Limited investigation and modern designation review have established unusual structural survival and research potential.
Why it is included
National importance rests on rarity, legible architectural detail and the capacity of a lowland broch to test how northern building traditions, exchange and social display operated farther south.
What to notice
- Massive circular wall surrounding the central space.
- Entrance passage with door checks and bar-hole.
- Cup-and-ring-marked stone reused beside the internal corridor.
Reading the surroundings
Woodland and masonry can be wet, uneven and unstable. Stay on recognised routes, never climb walls, light fires, remove stone, dig or metal-detect, and heed forestry work or temporary closures.
Timeline
- 4100–800 BC A cup-and-ring motif was carved on a stone later reused here.
- Iron Age Builders created the massive roundhouse and surrounding defences.
- 2025 Updated scheduling documented the monument’s survival and national importance.
What we know — and what remains uncertain
The broad Iron Age range does not provide a precise building date. Upper storeys, occupation sequence and the meaning of the reused carved stone remain interpretive questions.
