The stone church of Hollola was built between 1495-1510 during the third wave of Finnish grey stone churches. Church is one of the biggest medieval churches in Finland and important medieval landmark in Päijät-Häme area. According to Reformation policies, the interior was remodeled in the 17th century.
Archeologists have found remains of the Iron Age settlement around the church. Area has been some kind of administrative and commercial centre for local people.
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.
