Penrice is the largest castle on the Gower and has a number of unusual features. The keep, gatehouse and much of the surrounding walls stand high but in a ruinous and ivy-clad state. The keep has a diameter of 9.7m over walls 2.1m thick. It contained a single room with three windows and a latrine but no fireplace over an unlit basement.
It was later raised without any extra living space being provided and a unique single storey chemise with a flat roof and parapet added towards the court. The hall lay on the upper storey of an adjacent range added outside the original curtain. Only the ivy-covered inner wall survives, with fragments of a late medieval porch towards the court. The layout of all the rooms is unclear.
The gatehouse has a square block within the curtain wall and a pair of three storey square towers with rounded outer corners projecting from the curtain. The curtain wall varies somewhat in thickness and is much rebuilt on the east side where there is a later medieval dovecot.
Penrice Castle is on private land, but a public footpath allows viewing of portions of the curtain and towers.
One of the closest to Bryngwyn is Weobley castle, also home to a mountain boarding range. Work began on the current structure of Weobley castle in the fourteenth century, and much of it is still remains.
During a visit to the castle be sure to check out the exhibition: Weobley: A Gower Castle and the Peninsula through the Ages, which tells the story of the castle.
Pennard Castle is situated on Pennard Hill overlooking the valley leading to Three Cliffs Bay, is perhaps one of the most stunning of Gower's Castles, offering stupendous views of the countryside around.
It is thought to have been built by Henry de Beaumont, in the twelth century with a bank and a ditch end of the fourteenth century due to erosion and later rebuilt with local stone.
This is a superb Gower castle set in a small park in the Mumbles, and, for a while, was the seat of the Gower Lords. Built in the Twelth Century, what was originally a wooden castle endured a violent early history, twice being burnt by the Welsh. Some sources say it was founded by Henry de Beautmont, others by William de Londres of Ogmore Castle.
Several of the castles in Gower are thought to have been started by Henry de Beaumont, who had been made first Earl of Warwick by his friend Robert the Conquerer for his role in supressing the rebellion of 1088.
It was Henry de Beaumont who captured the Gower peninsula for England, and who was granted the Lordship of Gower in 1107. Some sources say that Henry built the castles at Oystermouth, Swansea and Llanhridian and possibly Pennard Castle.
Oxwich castle is a magnificent Tudor mansion created by Sir Rice Mansel and his son Edward stands on a headland above the wide sweep of Oxwich Bay. The house is known as Oxwich Castle, and there indeed appears to have been an earlier true stronghold on the site. Philip Mansel is recorded as holding the site in 1459. However, the remains we see today are best regarded as those of a mock-fortified manor house, with clear evidence of sumptuous accommodation, and raised during the peaceful and prosperous years of the 16th century.
