Korcula Old Town is the main attraction of Korcula Town in Croatia (in former Yugoslavia) ? a medieval walled city positioned on an oval-shaped swelling of land pointing deep into Peljesac Channel. The Old Town itself is grooved with a succession of narrow streets that branch off the spine of the main street like the fish bone. The fishbone shape was used in Korcula Old Town design to reduce the effects of wind and sun and provide citizens with sheltered and comfortable accommodation. The architecture in the Old Town is mainly influenced by Venetian Renaissance (see palaces in Korcula). The Old Town centre is dominated by the splendid St Mark?s Cathedral built in the Gothic-Renaissance style, completed in the 15th century (by Marko Andrijic) at the place of other church from the 13th century.There is a local legend that Marco Polo was born in Korcula Town.
