Alushta is a resort town in Crimea, Ukraine, founded in the 6th century by Emperor Justinian. It is situated on the Black Sea on the road from Gurzuf to Sudak, as well as on the Crimean Trolleybus line. The area is notable for its rocky terrain. There are also vestiges of a Byzantine defensive tower and a 15th-century Genoese fortress. The town was called Aluston (Αλουστον) in the Byzantine Empire, and Lusta during the Genoese rule. Adam Mickiewicz dedicated two of his Crimean Sonnets to Alushta.
