Trogir is a UNESCO World Heritage Site located on a small island in the Trogir Channel, 28 km from Split. The island is connected to the mainland by two bridges and to Čiovo island (which stretches south across the channel) by a third. The entire old town fits on approximately 0.5 km² of the island.
The Radovan PortalThe Cathedral of St Lawrence (Katedrala sv. Lovre) in the main square is the architectural centrepiece. The west entrance is the Radovan Portal, completed in 1240 by master carver Radovan, the most significant example of Romanesque carving in Croatia. The portal is around 10m tall and shows a complete carved programme: the zodiac signs, hunting scenes, biblical narrative, and the figure of Adam and Eve at the base columns. Cathedral entry: €5.
The cathedral interior has a 15th-century chapel of St John of Trogir with polychrome stonework by Nicola di Giovanni Fiorentino. The bell tower can be climbed (a narrow medieval staircase, worth it for the view of the Trogir channel).
The Kamerlengo FortressAt the western tip of the old town island, the 15th-century Venetian fortification (Kaštel Kamerlengo) is directly on the sea. Entry: €5. Open space inside the walls used for summer concerts and events. The top battlements have a direct view of the Šolta channel, the ACI Marina Trogir, and the Čiovo island coast. Takes 20 to 30 minutes to visit.
The main square and RivaThe Trg Ivan Pavla II (main square) has a covered loggia, the town clock tower, and St Sebastian's Church, all immediate neighbours to the cathedral. The 15th-century loggia has carved capitals by Nicola di Giovanni Fiorentino (same sculptor as the Trogir cathedral chapel).
The Riva (waterfront promenade) runs along the mainland-facing side of the island. In season, this is café and restaurant tables directly overlooking the mainland connection bridge and the ACI Marina.
With 2 hours: what to prioritiseRadovan Portal at the cathedral entrance, 15 minutes. Cathedral interior, 20 minutes. Walk the Riva, 10 minutes. Main square and loggia, 10 minutes. Kamerlengo exterior view, 10 minutes. That accounts for the main visual content without climbing the tower or entering the fortress.
With a full day: what the shorter visit missesThe streets behind the main square, the grid of medieval lanes between the cathedral and the west fortification, has detail that a quick visit misses entirely. The Chapel of St John houses Trogir's most important artwork. The Dominican and Benedictine monasteries (both accessible with a small entry fee) have interiors that show the density of medieval religious patronage.
The Čiovo island across the southern bridge has a beach strip (Okrug Gornji) 4 km from the old town, a practical afternoon swim location after a morning of historical sites.
