Château de Trémazan

Château de Trémazan is a castle ruin positioned on rocky terrain near the Breton coast, featuring a square central tower with four habitable levels. Thick defensive walls surround the structure, showing it was built to control and defend this coastal area.

The castle developed on foundations dating to the 6th century and served as the main residence of the du Chastel family. Around 1220, it suffered significant damage that reduced its role as a home, though it retained strategic value.

The castle reflects the power of local noble families who shaped the region for generations. Its stone structures remind visitors of the social hierarchy and defensive needs of medieval Breton society.

The ruin sits on rocky coastal terrain and is accessible, though it offers limited facilities on site. A local preservation group organizes guided visits and maintains the structure.

A partial collapse in 1995 unexpectedly revealed internal chamber systems and architectural details within the main tower. This accidental discovery helped researchers better understand how spaces were arranged and used.
