Husaby Church is one of the most interesting historical sites in Sweden. The first stave church was built probably in the 10th century. Olof Skötkonung, the first Christian king of Sweden, is rumoured to have allowed himself to be baptised at a well by the church in 1008. Husaby was also the seat of bishop until 1150s.
The present church was built in the early 1100s and influenced by German and English missionaries. Architecturally, it is remarkable for its steep walls and high towers, arguably the only Romanesque architecture in Sweden of that kind. Arches were added in the 15th century.
The most interesting artefact inside is the medieval bishop’s seat. There are also two graves, which (according to tradition) belong to King Olof Skötkonung and his wife Estrid.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
