The remains of an Iron Age hillfort can be seen on the grassy mound of Twyn y Gaer. Though little remains of this ancient structure, it’s easy to see why our ancestors picked this naturally defensive spot to settle. On a clear day there are stunning views all around; the peaks of Pen-y-Fan and Corn Du; the Black Mountains; the river yak.
