One of the many fort walls going around the island’s weak points. The stone walls appeared to be at least three metres thick. No surprises it’s still standing after all those wars.

Oh yea, and that gate is a human powered drawbridge, with its doors lowered.

As I went around the island, I realised it’s truly an open museum. This place has artifacts from medieval forts (with moats and drawbridge) to WWII anti-aircraft guns.
