Penlle'r Castell

Penlle'r Castell is an historic ruin on the summit of Mynydd y Gwair[1][2] in the far north of the City and County of Swansea.

The Penlle'r Castell site was probably a late 13th-century stronghold garrisoned by one of the Marcher Lords.

However, there is no firm evidence as to the date of its construction, but it is believed to be the fortification referred to as the "New Castle of Gower" which was attacked and destroyed in 1252.

Penlle'r Castell is in an ideal position for monitoring the actions of the lords of Is Cennan, resident on the north side of the River Amman, and preventing their encroachment into northern Gower via this important ridge route.

[4] Now visible at this site are a series of impressive earthworks with deep ditches and some fragments of the stone buildings that must have topped them.
