Boulby sound mirror
The grade II listed sound mirror at Boulby on the Yorkshire coast was built in about 1916, during the First World War. It is on top of a hill, facing out to sea.

The mirror is of the same design as the one at Redcar, but different to the Kilnsea one.

To give some idea of the size of the mirror, I'm about six foot tall.

The mirror is adjacent to the road in a field on top of a hill. The rear of the mirror can easily been seen from the road.
Location
The mirror is west of Boulby Barns Cottage on Boulby Bank. Map. It is in a field between two farms, and is on land belonging to the westernmost. The rear of the mirror is clearly visible from the adjacent minor road.

- Tees Archaeology has an aerial photo of the mirror (it's at the near end of the darker green field to the right-hand side).
It was probably constructed in 1916. The structure is made from reinforced concrete set with corrugated iron shuttering. The sound mirror is a squared U shape in plan and is 17ft high. It survives in good condition although there is some decay to the concrete.
