Tvrdalj Castle was the summer residence of Petar Hektorović, the Croatian poet (1487–1572). During the 16th century, the island of Hvar came under attack from the Ottoman Turks. Hektorović, one of the local nobles, undertook to fortify his house so that it could act as shelter for the local citizens.
Tvrdalj is a well-preserved Renaissance building, with a long closed facade on the seaward side, to protect it from attack. The interior courtyard contains a sea-water fishpool, enclosed by a vaulted and arcaded terrace. Next to it is a tower with a dovecote. The living quarters, together with the servant quarters, and several wells, are arranged around the pool. Behind the main buildings is a walled garden where Hektorović cultivated herbs and medicinal plants.
A series of inscriptions are set into walls of the mansion in Latin and Croatian. Those in Croatian are considered to be some of the oldest extant.
In 1571 Stari Grad was again attacked and Tvrdalj was set on fire by the Turks. A year later, Petar Hektorovic died and the damaged Tvrdalj was divided between his relatives. Following provisions in his will, there were gradual improvements made. However, in 1834 the Venetian laws lapsed and Tvrdalj experienced massive construction works: the south wall of the complex was removed, vaults constructed around the pool, a second floor added on either side of the tower, and new two-storey houses were built. The bay in front of Tvrdalj was filled in as part of the harbour improvements. In the 20th century, further major changes were experienced in 1901 when the eastern wall was demolished and houses built over the vault and cistern which is still part of the Tvrdalj entrance.
References: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.
