Many visitors have been enchanted by Rovinj and its beauties. At the 100-year-old institution of Rovinj Aquarium one can admire fauna of the Adriatic Sea. The Rovinj coastal area is well articulated with numerous bays, creeks, and capes. There are places of great natural and ecological value: forest park Punta Corente-Muntrav, St. Andrea's archipelago, the Palud marsh, the Limski kanal Fjord, and Monfiorenzo cave. The antique city center presents a unique Venetian urban and architectural model, built upon late antiquity and high medieval foundations. The historic nucleus is up on a hill, on a very narrow building area of former island, with houses bunched together up to the baroque St. Euphemia Church - which has a slender bell tower dominating the city. The ample Valdibora Bay is on the North side, and the pictoresque Bay of St. Catherine is on southern side of the city. Rovinj has numerous sporting associations, important scientific and research institutions, museums, cultural attractions, and educational instituitions.
