In far-off antiquity, the fort of Crepsa had stood on the site of modern-day Cres town. With time, a settlement had grown up around it, varying in size and shape, until the town's boundaries were finally settled during the Middle Ages with the construction of curtain walls. This age is brought back to vivid life by the sight of the three town gates and the round tower which was once the high point of the Venetian defense and early warning system.
Several churches and Renaissance palaces can likewise bear witness to the tumultuous past of Cres. Of particular note are the town loggia with its pillory, the twelfth-century Church of Saint Isidore and the fifteenth-century Arsan palace, which houses the Museum of Cres.
Valuable monuments are scattered throughout the spacious Bay of Cres, girded with a rocky wreath, and a major landmark are the rows of houses along the old town core.
