Antoni Gaudí's ambitious project remains, as of today, unfinished, which by no means takes away its massive popularity, receiving over 4.5 million visitors every year. The Basílica de la Sagrada Família, or simply La Sagrada Família, is a large unfinished Roman Catholic minor basilica, considered the best example of Modernist architecture. Meticulously crafted to embody the Christian faith through composition, sculpture, and individualistic, offbeat design, this masterpiece is the kind of attraction that has to be experienced to be believed.

The Domus del Chirurgo, also referred to as the Surgeon's House, is an important archaeological complex of over 700 square metres that includes several buildings. The Surgeon's House preserves the remains of an ancient Roman house dating from the second century AD. The most outstanding find is a collection of 150 surgical instruments.

Gudmundstjärn, located 30 km west of Sundsvall, is one of Sweden's last preserved self-sufficient settlements. Between 1779 and 1944 the fields here were farmed by five generations. No roads connected the homestead to the outside world. The 22 preserved buildings have been declared historical monuments, and the area is now a nature reserve.
