Mõdriku estate (Mödders) was first mentioned in 1470. Over the centuries, it has been the property of various Baltic German families. During the 20th century, it has been used by various schools. The building traces its oldest parts to the 17th century, but has been extensively enlarged and rebuilt both during the 1780's and 1890's.
The manor was the home of several successive generations of the von Kaulbars family, including Russian general and explorer Alexander Kaulbars. An ancestor to him, R. A. von Kaulbars (reputedly a great patriot) put up the column commemorating the French-Russian War of 1812 that is still visible in the manor park.
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.
