St. Michael's Church in Fulda is considered to be the oldest Holy Sepulchre church in Germany, built in the Carolingian architectural style (Pre-Romanesque) by the abbot Eigil in the years 820-822. It served as a burial chapel to Fulda monastery founded in 744, which was one of the prominent cultural centres of the early Middle Ages. St. Michael stands in the neighbourhood of Fulda cathedral, and the architect was probably the monk Racholf (d. 824).
The rotunda and crypt remain preserved from this time. In the 10th and 11th century, the church was extended from the rotunda, and a west tower was built. In 1618 the roof over the rotunda was rebuilt with a conical roof, and in 1715-1716 a chapel was added to the north side. Wall paintings in the interior date from the 11th century.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
