Another site once at the heart of Tarsatica, as the nearby remains of Roman spas testify. St Mary of the Assumption dates back to the Middle Ages, and has since then undergone many phases of rebuilding and adding to, resulting in a right old mix of styles, but not changing the fact that this is a much-loved place of worship. This was once the main church of Rijeka, locals still call it Vela Crikva, or “The Big Church”, while they call its tower kosi toranj, or “the leaning tower” because it’s out of true by 40cm. St Mary’s interior is full of beautiful baroque stuccowork, including the ceilings. This is a good church to attend if you want to get the feel of a local mass: July 08:00, Sun 08:00, 10:00, 19:00; August 19:00, Sun 08:00, 10:00, 19:00; rest of the year Mon - Fri 08:00, 18:00, Sat 08:00, Sun 08:00, 10:00, 18:00.
