If the Italian coastline gets you all aglow, then underrated Sibenik will certainly follow suit. Croatia's oldest native town on the eastern shores of the Adriatic Sea, is a gleaming example of medieval history. Lose yourself in the maze of steep backstreets and cobbled squares. For views across the Dalmatian coast, climb to the top of not one - but two - Venetian forts built in the 16th century to repel Ottoman invasion. In the Old Town, the Cathedral of St James is the city's crowning glory. Admire the jaw-dropping fusion of Gothic and Renaissance styles in the vast interior. Afterward, stroll along the Riva and sip a biela kava (white coffee) at one of the harbourside cafes, or find tranquillity in the hidden St Laurence's Medieval Monastery Garden. Sibenik is also the gateway to Krka National Park, with its breathtaking scenery and archaeological remains.
