In the centre of what was once a large fortress is an earthen mound with the remains of a thick-walled building on top of it, which may be all that’s left of an earlier keep. Links to Caerphilly Castle too - see plaque in the gatehouse.

In the beginning, as a castle of earth and wood in the early 12th century, it was quickly fortified in stone before being further strengthened with a curtain wall in the early 13th century. Unusually, the later additions have not obscured the castle’s earliest defensive features, with the banks and ditches built at Ogmore’s birth still clearly visible. Another original feature is the deep ditch around the inner ward, designed to fill with sea water at high tide.

Lllanblethian is a quaint and picturesque village that sits above the River Thaw in the Vale of Glamorgan. It's an ancient village, outdating the nearby market town of Cowbridge, and hosting a number of beautiful historic buildings. The village is home to St Quentin's Castle, a 14th-century castle perched upon a hill, a church that dates back to the 12th-century dedicated to St John the Baptist, and an early 18th-century great house that sits along the river.

Such a beautiful place and quite an emotional and spiritual place for me. As Grace mentioned above it has a chapel. That chapel is called Penrhiw chapel, it was built in Drefach Felindre in West Wales. My father lived a very short walk from that chapel, the entire family used to worship in it and my cousin ended up preaching in it (he is alive today at 95+). My dad and his brothers all went away to fight in WW2, they would come back and find solace in 'Penrhiw' for the ones who didn't come back. It was really the spiritual fulcrum for my whole family. I guess I am lucky as every time I go to St Fagan's I can go to Penrhiw and speak to my father once more....

These stepping stones have quite a history. Before the suspension bridge for pedestrian use was built there was, at that spot, a series of stepping stones. When the bridge came into use these stones were lifted and placed near Ogmore Castle, where they remain today, keeping their original name: Stepsau Teilo. At one period towards the end of the last century a competition developed to see how quickly the crossing could be made without falling into the river. Many tried to take the stones at full speed and, cheered on by onlookers there were several slips.
