Henry’s Hole

The entrance to Henry’s Hole is a natural rift at the foot of a quarried cliff in the garden
of No. 4, The Tynings, Box Hill. The entrance rift leads to a small area of mine workings,
actually part of the Box Freestone Mines complex but not connected to the main workings. The
mined passages are low and bouldery, though they do give access to further passable gull rifts.

Each rift is generally narrow and of only a few metres length. The most interesting feature of
Henry’s Hole is a mined passage with a solid rock roof which passes underneath a gull rift
