While walking along the coast towards the Monastery's entrance gate, the visitor first sees the oldest parts of the building complex. He passes beneath the sea walls, where the guest house that will welcome him is located. Today, visitors enter the Monastery through a helical passage at the southwest corner of the walls. Its shape is defined by the two tower-like buildings which border it: The so-called St Stephen's tower at the inner end of the passage, and the Holy Apostles tower at the outer. The latter tower is dated to 1661/2.
