The palazzo del Capitaniato was designed by Andrea Palladio in 1565 and built between 1571 and 1572. The palazzo is currently used by the town council. It was decorated by Lorenzo Rubini and, in the interior, with frescoes by Giovanni Antonio Fasolo. Since 1994 the palace has been part of the UNESCO World Heritage Site of the 'City of Vicenza and the Palladian Villas of the Veneto'.
The Palladian loggia replaced an analogous building which had stood on the same site from the Middle Ages, and which had already been reconstructed at least twice during the Cinquecento: a covered public loggia on the ground floor and an audience hall on the upper storey. The new construction became economically viable in April 1571 and works began immediately. Palladio supplied the last drawings for the moulding templates in March 1572 and by the end of that year the building would have been roofed, since Giannantonio Fasolo could paint the lacunars of the audience hall while Lorenzo Rubini could execute the stuccoes and statues.
While the upper hall displays a flat, coffered ceiling, the ground-floor loggia has a sophisticated vault covering, certainly to better sustain the weight of the hall. The overall design is extremely sophisticated, as witnessed for example by the portals which open within the niches and follow their curvature.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
