The earliest record of the Riilahti village is from the 15th century and first manor was established about one hundred years later. From the year 1725 Riilahti has been owned by the noble family Aminoff. The present manor house was built in 1803-1806 by Pehr Granstedt. It’s surrounded by the large English style park.
Sweden and Russia fought massive naval battle near Riilahti in 1714. Today there’s a monument of the battle near the manor. Riilahti provides nowadays conference facilities, horse riding and cottage rents. Guided tours are available for groups.
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.
