15. CULVER HOLE

From the Gower clifftops, among sea thrift and yolk-yellow gorse, it would be easy to miss the fact that a medieval dovecote is secreted in the rock beneath your feet. Seemingly of the cliff, a windowed wall has been built across a cave and at low tide you can scramble inside. The pigeons, kept for eggs and fresh meat, would have nested in the honeycomb-like recesses built into the wall. In the gloom, the sound of the sea is softened, and your eyes are drawn to the windows – circles of sky, fringed by vegetation.
