Ratho Mains Thrashing Mill

Ratho Mains Farm, Ratho, Midlothian.

Tunnels / Chamber, probably early 19th Century.

A 5.8 m-deep entrance shaft drops down to tunnel system. Downstream it runs east for c.400 m to surface below the far side of the minor road heading south from Ratho. Going upstream the roof lowers until it is 70 cm high then steps upwards just before entering a (water wheel?) chamber. This is 15 m from the entrance shaft and is well built of dressed sandstone blocks. It is 6.1m long and 3.4 m high to a poorly constructed arched brick ceiling. Just above the entrance there is a capped shaft in the roof that was radiolocated to a room built onto the side of the main steading.

Alternative Names: None recorded.
