There are four fogous which survive close to their original shape:

• Halligye (713254) on the Trelowarren estate near Garras is the largest and best preserved. This is the cathedral of them all
• Carn Euny (402289) near Sancreed is situated in an Iron Age village. This contains a unique circular corbelled chamber off to one side of the fogou
• Pendeen vau (384355) close to Cape Cornwall. This is in a farmyard alongside the house in which noted antiquarian William Borlase lived. One hopes that it was the inspiration for his interest in archaeology rather than a folly constructed at his request
• Boleigh (437252) near St Buryan. This is similar in size to Pendeen

Four are severely damaged but retain enough detail to be worth a visit:

• Piskey’s Hall (728300) or Trewardreva
• Lower Boscaswell (377348) just outside Pendeen. This is sadly decayed and only the main and side entrances survive
• Boden (768240) close to Manaccan on the Lizard. This is an open channel with shillet side walls and what looks like a Carn Euny-style chamber
• Porthmeor (434371) near Gurnard’s Head is roofless. Like Carn Euny it is closely associated with a courtyard house

…  five which are partly or wholly destroyed:

• Higher Bodinar (415320) near Newbridge, half way from Penzance to St Just which is simply a grassy depression
• Chysauster (472350) in the hinterland north of Penzance. Sadly this has been backfilled by English Heritage for safety reasons
• Castallack (452253) just outside Lamorna
• Treveneague which was recorded in 1866. Its location was lost for many years but was identified by Time Team in 1995
• A roofless fogou was discovered at Penhale Round, far to the east of the known limit of extant fogous, but this was destroyed in the building of a budget hotel

… and lastly, we reluctantly include:

• Bosporthennis beehive hut which is ‘generally regarded’ as an above-ground fogou (although we remain to be convinced)
