The city of Korcula lies beside the sea on the north-east end of the island. The old medieval part of the city was built on a small oval peninsula, a Baroque suburb spreads under the old city walls, and newer town quarters stretch along the shore to the east and west of the old centre. Today the city has about 3,000 inhabitants, most of them living in new parts of the city.
Korcula is the seat of the administration of the Toum of Korcula that includes the city, part of the island and four villages: Zrnovo, Pupnat, Cara and Racisce, with a total of about 6,000 inhabitants. Korcula has many social, cultural, economic and health institutions and organizations: a kindergarten, elementary and secondary school (grammar school), museum, library, medical centre, tourist agencies, banks, pharmacy, hotels, shipyard, shops, restaurants and so on. It also has cultural and performing societies that foster choral singing and folk dancing, and sports societies.
The old city nucleus is protected as part of the national heritage. Its "herring-bone" ground plan is very specific. The city was built on a small peninsula joined to the mainland by a narrow strait in the south. The land configuration is similar to that on the indented mainland and rises gently from sea level. Construction was adapted to the lie of the land, and the main street stretches from south to north down the centre of an ellipse. Narrow streets that climb from the seashore to the top of the hill lead to this axis on both sides (from west and east), and at the top is the main city square -the centre of social and religious life in this medieval city.
There is another small square beside the city gate in the south city wall, where the Town Hall stands, and nearby the Fontik (granary) and the Governor's Palace. The main street joins the two squares, this is where the shops were, while the craftsmen's workshops were in the side streets. The distribution of the streets is regular, almost geometrical. Those leading west are straight, those leading east curved, because the town planners bore in mind that this cramped city had to be aired. They opened it to the pleasant summer west wind (maestral) , and protected it from the cold winter north-easterly gales. However, defense was paramount in building the city, which is best seen in the fan-like distribution of streets in the north enabling defenders to quickly reach any point on the towers and walls. It is also interesting that all the streets but one have stairs, and all are well paved. The old names of all the streets have unfortunately not been preserved, but most of them were named after the distinguished families that lived in them.
