St John's Fortress

The fortress of St John is a structure on the south-eastern side of the old city harbour. This fortification watches over and protects the very entrance to the harbour. 

The fortress in its current guise dates from the 16th century, with rounded, sloping walls facing the sea and sheer sides towards the harbour, displaying an array of cannon ports.

In modern times, this fortress houses the Maritime Museum and Aquarium.
