As it stood in 1531
The shape it held in its prime.
A squat, square three‑storey stone château, about 28 m to a side, set directly on sheer pale limestone cliffs rising from the Mediterranean. The masonry is warm, roughly hewn ashlar; three large cylindrical towers project from the curtain walls and are pierced by rectangular gun embrasures and narrow slits. Crenellated parapets and low gun platforms run along the cliff edge. The island footprint is small and rocky with the fortress dominating the shore against deep blue sea.
