San Xavier del Bac Mission, located 10 miles south of Tucson on the Tohono O’odham Nation, is an iconic example of Spanish colonial architecture. Known as the “White Dove of the Desert,” its striking white facade contrasts beautifully with the surrounding desert landscape. Built between 1783 and 1787, the mission blends Moorish, Byzantine, and Mexican Renaissance styles, featuring intricate carvings, vibrant murals, and a gilded retable depicting biblical stories. Still an active parish, it holds daily masses and remains a spiritual center for the Tohono O’odham people. Extensive restorations have preserved its historic beauty, making it one of the best-preserved Spanish missions in the U.S. Visitors can explore the mission’s interior, join free docent-led tours, or browse crafts and frybread sold by local artisans.

The Church of St Donatus is considered by many the symbol of Zadar. This majestic circular building is one of the finest examples of Byzantine style in the whole country. Nowadays it's no longer used as a church but as a venue for cultural and musical events. The ground floor houses a permanent exhibition of the medieval collection. The first floor is dedicated to the permanent exhibition of the ancient collection. The second floor shows off the permanent exhibition of the prehistoric collection.

The grand, fairy-tale castle-like main building in Timrå was built in 1883–1885 as a summer residence for the timber magnate Fredrik Bünsow, who was one of Sweden's most powerful timber barons at the time. The architects were Isak Gustaf Clason and Fritz Eckert. Clason is known for designing the Nordic Museum and Hallwyl Palace in Stockholm. The beautiful castle (or Villa Merlo, as it is actually called) is now a cultural heritage site and houses Svenska Cellulosa's central archive. In the summer, you can take a guided tour to see the many rooms and halls that still retain their former glory. Even the garden alone is well worth a visit.
