Wiki

Newcastle Castle was initially constructed as a ringwork 1106 by William de Londres, one of the legendary Twelve Knights of Glamorgan, as part of the Norman invasion of Wales. William de Londres was a knight loyal to the Norman baron Robert Fitzhamon and the Newcastle defences marked the most western extent of Fitzhamon's lordship.[1] It is one of three castles built by the Normans in the area at the time, the others being Coity Castle and Ogmore Castle

The castle's most outstanding feature is its complete Norman doorway (shown at left), which greets the visitor approaching the castle from the south. It is late 12th-century, contemporary with the curtain wall. On the inside it is quite plain, but the outside is given fine decorative treatment. Once inside the curtain wall, the circuit of which is complete, the nature of the castle becomes apparent. It is a courtyard castle, roughly circular in plan, with two mural towers built into the curtain wall on the south and west sides. The curtain wall, which was built in straight sections, is impressive and stands to its full height on the west side.
