Koper, one of Slovenia’s oldest towns, was once an island in north-western Istria.  Today’s city centre is limited to the ancient island, while its present appearance is the result of a 2000-year-long continuous development that began in Roman times.

According to tradition, the first bishop of Koper was St Nazarius. He was born between 470 and 480 in the Istrian village of Elpidium – Boste – Boršt. St Nazarius was consecrated Bishop of Koper in 524. The year 524 is therefore also associated with the foundation of the city of Koper.

This year, Koper celebrates its 1500th anniversary. Throughout the year, a series of cultural events will take place; from exhibitions, scientific symposia, conferences and public debates, to theatre festivals, publications and other interesting activities.

A detailed calendar of events can be found below:
