The gate of the Höpken bastion

Though this gate, you can enter the main courtyard of the island of Sisusaare. The Höpken Bastion is part of the island's inner defense ring and its oldest fortification, after all, its construction began in 1750. The bastion has only one front and an outgoing corner and, with its right flank, is adjacent to the Commandant's House in the Main Courtyard.
