Undredal Stave Church was built in the middle of the 12th century. The church has been moved from different locations and reconstructed a few times. Around 1850 the building was extended to the west with the addition of a clock tower and porch. In 1913 there were plans to dismantle the church and move it to a museum in Kaupanger, but this never happened. Instead it was reconstructed in 1984 and under extensive maintenance work. Inside the church, the ceiling is decorated with biblical figures and angels. The church with 40 seats is the smallest church Stave church in Norway.
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.
