Bourtzi Castle in Nafplio Harbour, Greece

Overlooking the tranquil azure waters of the Argolic Gulf lies the historic fortress known as Bourtzi Castle within the harbor of Nafplio city, Greece. This formidable structure was built by Venetian architects during the late medieval period to protect the entrance from pirate attacks. Today it stands majestically amidst boats moored at its dock, underlining both maritime history and Greek architectural prowess against an idyllic backdrop of distant mountains and clear skies.
