Belvedere This is the only loggia in Istria that is situated by the sea. It probably rests on an older part of the defensive walls (ruins of a tower). Presumably constructed in the 16th century, the Loggia was renewed in the years 1860 and 1930. Originally it had a hipped roof. To the West of the Loggia, the vaulted passage Porta a marina leads to the sea. The keystone of the arch bears the date 1649, but the entire construction was moved to this place from its original location in the north-western part of the city at the time of the establishment of the new city park in the 19th century.
