Helga Trefaldighet (Holy Trinity) Church was inaugurated in 1302. It replaced the previous church of local Ullerås parish. The church is made of grey stone and brick and it was originally a three-nave basilica. The western tower was added in the 15th century. The church was damaged badly by fire in 1702.
The interior is particularly notable. It is decorated with paintings by the famous medieval artist Albertus Pictor, which were created in the second half of the 15th century. Of particular interest is the depiction of The Visitation, regarded as one of the finest surviving medieval paintings in Sweden.
The chapel of Notre Dame du Haut in Ronchamp is one of the finest examples of the architecture of Franco-Swiss architect Le Corbusier and one of the most important examples of 20th century religious architecture. It was built between 1953 and 1955. The chapel is a working religious building and attracts 80,000 visitors each year.
Notre Dame du Haut is commonly thought of as a more extreme design of Le Corbusier’s late style. The chapel is a simple design with two entrances, a main altar, and three chapels beneath towers. Although the building is small, it is powerful and complex. The chapel is the latest of chapels at the site. The previous chapel was completely destroyed there during World War II. The previous building was a 4th-century Christian chapel. At the time the new building was being constructed, Corbusier was not exactly interested in “Machine Age” architecture but he felt his style was more primitive and sculptural. Also, he realized when he visited the site that he could not use mechanized means of construction, because access was too difficult.
