It lies just west of Brompton on the A489 between Church Stoke and Newtown.

The hamlet is notable for the fact that it is impossible to reach any other settlement in England (except Brompton) by road without first passing through Wales.

Public footpaths are the only access which links it with the rest of England.

The remains of a Roman fort have been discovered in the hamlet.
