The Guora Gate, commonly known as Megali Porta (Great Gate), is the only surviving entrance of the Venetian fortifications of Rethymno.

Built between 1566 and 1568 under the rectorship of Jocopo Guoro, it served as the main inland entry point to the city, known as Porta Reale. Originally, it was an imposing structure decorated with pediments and the Lion of Saint Mark, the symbol of Venice. Although most of the city walls were demolished in the early 20th century to allow for urban expansion, the Guora Gate was preserved. Today, it stands as a symbolic portal, connecting the modern city of Rethymno with the historic atmosphere of the Old Town. Passing through its arch is like stepping back in time, leading directly into the heart of the Venetian district.
