Towering over the Haga neighbourhood, in central Gothenburg's southern part, you can find one of the city's two remaining forts. It was built in 1698 to protect Gothenburg from possible Danish attacks, which fortunately never happened. Although there is no access inside the fort, it's still worth your time since the view over the city is spectacular from the hill where it's beautifully located.

Housed within the historic Episcopal Palace that dates back to the 10th century, the Museu d'Art de Girona boasts the most important art collection in the province. Its chronologically arranged galleries guide visitors through Catalan artistic evolution, from striking Romanesque altarpieces and Gothic gold-leaf panels to Renaissance sculptures and Modernista works by artists like Santiago Rusiñol. Notable highlights include the 9th-century liturgical treasures from Sant Pere de Rodes, a 15th-century illuminated martyrology, and hauntingly beautiful Romanesque woodcarvings. The palace itself is a masterpiece. Don’t miss the medieval gaol and the serene gardens. Room 8, draped in Gothic religious art, feels like stepping into a cathedral shrine. With over 8,500 works and a programme of temporary exhibitions, this museum offers a profound dive into the region’s soul, all within a stone’s throw of Girona Cathedral.
