Korčula Cathedral, Gothic cathedral in Korčula, Croatia.

St. Mark's Cathedral sits at the highest point of the Korčula peninsula and displays a Gothic facade with stone carvings, a central rose window, and multiple side aisles. Inside, tall columns draw the eye upward toward the decorated vaulting overhead.

Local masters built the cathedral from the early 15th to the mid-16th century, and Bonino da Milano carved the portal. In 1557 an organ by the Colombi workshop was installed, painted by a pupil of Tintoretto. The diocese of Korčula was suppressed in 1828 and merged into Dubrovnik, ending the building's cathedral status.

The building shapes the spiritual life of the island and continues to host religious services and processions that mark the yearly calendar of faith. Worshippers gather here for special occasions, maintaining an active religious community.

The building welcomes visitors daily, with longer hours in summer and limited access during winter months. Photography inside requires advance permission from the staff.

The cathedral keeps a late 14th-century icon of the Madonna of the Island (Gospa od Otoka), credited since 1571 with saving Korčula from an attack by the Ottoman fleet. The 1557 organ was painted by a pupil of Tintoretto, while Tintoretto himself painted the altarpiece showing St Mark with St Bartholomew and St Jerome, patrons of Korčula.
