Sudak or Sudaq (Crimean Tatar: Sudaq; Ukrainian and Russian: Судак) is a small historic town located in Crimea. Today it is a popular resort, best known for its Genoese fortress, the best preserved on the northern shore of the Black Sea.
It is believed that the city was founded in 212 AD by Alani settlers. Greek merchants from the Byzantine Empire founded Σουγδαία (a reference to Sogdia) in the 3rd century. In the 6th century, the Eastern Roman Emperor Justinian I ordered the construction of a fortress.
It became an important location for trading on the Silk Road in the 12th and 13th centuries
