Jutting out into the St Anthony’s Channel, the narrow neck of water that leads from the Šibenik Channel to the open sea, the smooth-pointed triangle of St Nicholas’s Fortress is one of the most elegant military buildings anywhere in the Adriatic. It was built by Venetian military engineer Gian Girolamo Sammicheli in the mid-16th century to protect Šibenik from Ottoman naval attacks. In 2017, it was included in UNESCO’s World Heritage List making Šibenik only one of five cities in the world with two ancient buildings listed. There are long-term plans to restore the fortress and turn it into a museum centre. You can visit St. Nicholas’ Fortress, organised by Priroda (Nature) a public body in Šibenik-Knin County. You leave by boat from the Krka berth on the Šibenik waterfront. Schedule and prices can be found at www.kanal-svetog-ante.com and the cost includes travel (20 minutes either direction), admission to the fortress (45 minutes sightseeing), tour guides, and multilingual materials. Total time approximately 2 hours.
