Rasbokil Church is a medieval church located north-east of Uppsala. The church appears to have been preceded by an earlier church, possibly a wooden church, and stones from an earlier building have been incorporated into the presently visible building. The current church was built at the end of the 15th century or around 1500 and has retained its original appearance largely unchanged. During the 18th century most of the windows were enlarged and the vaulting of the church repaired; at that time the frescos were also covered with whitewash, only to be uncovered and restored during a renovation in 1909-10 under the guidance of architect Sigurd Curman. A window was also made in the north wall of the church in 1870. The church is one of very few medieval churches in Sweden which has never been substantially rebuilt or altered.
The church is constructed of fieldstone with decorated brick gables. It has a yellow exterior with details painted whitem and the steep gable roof has a covering of shingle. The church has a simple floor-plan consisting of a single nave with two sections of star-shaped vaults, followed by a choir of equal width with a ceiling supported by a rib vault. The design is typical for countryside churches in Uppland built during the Middle Ages. The vaults were decorated with frescos probably during the 1520s by an anonymous workshop sometimes referred to as Rasbokilsmästaren ('the Rasbokil master'). In comparison with other church frescos in Sweden, some of the frescos have unusual themes, including e.g. depictions of the family trees of Jesus and Mary. The frescos have been described as being of 'distinguished quality'.
Most of the church's furnishings date from the time after the Reformation. These include the pulpit, which is from 1648 and given as a gift to the church by Colonel Jurgen Schildt after his homecoming from the Thirty Years' War. The altarpiece is also from the 17th century; its top part with a painting was restored in the 1930s after its Baroque frame was found in pieces in the belfry of the church. The decorated door of the church porch dates from the reign of King Gustav III of Sweden and the organ is from 1829.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
