The oldest parts of Follingbo Church are the nave and tower. They date from circa 1200 and together form an unusually accomplished example of Romanesque architecture on Gotland. Although lacking in ornamental sculpture, the tower and nave are well-proportioned and unusually professionally executed. The choir is later (late 13th century) and already Gothic in style, and also considered unusual for its kind. The choir replaced an earlier, Romanesque choir with an apse. The current choir instead has a straight eastern wall, adorned with a single tracery window, in which fragments of medieval stained glass panes remain. The sacristy was built in 1820-21.
Inside, the church has a painted ceiling, decorated at the end of the 17th century. Most of the furnishings are also from the 17th or 18th century. An exception is the undecorated baptismal font, which is medieval.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
