The present church at Hamre cannot be dated precisely. It was historically thought to have been built around 1622, but more recently an inscription on the old main door was found that suggests that it may have been built in 1585, in which case it is the first wooden church to be built near Bergen. Hamre Church was founded in 1024, and it was the main church for all of Nordhordland. There isn't much known about the original church building, but at some point it was torn down and a stave church was built to replace it. The stave church was replaced by the present church sometime around 1600.

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.
