St Quintins Castle

St Quintins Castle is a medieval fortress in Llanblethian, Wales, with a rectangular enclosure and thick defensive walls on elevated terrain. The surviving remains show foundations of a semi-octagonal tower and an ivy-covered gatehouse with visible portcullis slots and door mechanisms.

Herbert de St Quentin founded the initial fortification in 1102, which was later expanded with a stone keep in the late 12th century. This development shows how the site evolved from a basic fortress into a more heavily fortified stronghold.

The twin-towered gatehouse functioned as a local prison during the 15th century when the site was an administrative hub. Visitors can observe the gateway structure and grasp its role in the daily operations of that period.

The elevated location offers good views of the entire layout from various vantage points. Visitors should prepare for uneven ground and slopes, so comfortable walking shoes are recommended.

The River Thaw on the southern side formed a natural defensive line, making extra fortifications there unnecessary. This shows how medieval builders strategically used the natural landscape to protect their stronghold.
