Tinboeth Castle

Tinboeth Castle comprises the remains of a fortification on the River Ithon with preserved stone walls and a twin-towered gatehouse. The site contains multiple functional areas identifiable through earthworks and foundation remnants.

Roger Mortimer built this fortification in the 13th century at a strategically important location with water access. After his death, it passed to royal ownership and later declined.

The site shows how defense traditions carried forward across centuries as builders adapted earlier fortification designs to new needs. Walking through the remains, you can observe how Norman builders incorporated the ancient earthworks into their own structures.

The site stands roughly 18 kilometers from Llandrindod Wells and is accessible on foot from nearby areas. Visitors can see the gatehouse and wall foundations in place, providing a clear sense of how the medieval layout was organized.

Ancient hillfort earthworks were cleverly integrated into a medieval castle here, with the outer areas using Iron Age defenses. This layering of two different defense periods remains visually distinct on the ground.
