Chania's Old Town is considered Crete's most beautiful urban district, especially the crumbling Venetian harbour with its 15th century lighthouse ("Faros") and the Mosque of the Janissaries ("Giali Tzamissi", built 17th century). Many of the old buildings have been restored as hotels, restaurants, shops and bars, making the old town a lively and colourful place during the tourist period (especially May-September). The Splantzia quarter behind the inner harbour and the Venetian Arsenals is still largely untouched and very atmospheric. This atmosphere prevails throughout the old town during the less busy period of the year (November-March). The 1860 Greek Orthodox Cathedral ("Trimartyri") is located in a square facing the entrance to the 1879 Roman Catholic cathedral across Halidhon street. The Synagogue - Etz Hayyim in the Topanas District, has been restored in recent years after falling into disrepair during the post World War II era. The 1913 indoor market ("Agora"), a large building based on the market of Marseille, is on the edge of the old town and is popular with tourists and locals alike. Other interesting sights within the old town are the Kasteli Archeological Area (Kanevaro), the Great Shipyard ("Arsenali"), the Fort Firca, the Gate and Bulwark Subbionara, The Gate of the Renier Mansion and the Turkish Minaret of Achmet Aga.
There are also several old churches - apart from the cathedral and the Catholic church - like the small Venetian temples of St. Rocco, San Salvatore, Agioi Anargyroi, Agia Aikaterini as well as Agios Nikolaos church in Splantzia district.
