Toppeladugård was originally farm of the Häckeberga castle. It was divided as an estate in 1720 by Christina Piper. The current two-storey main building and two wings were built in 1918-1920 by the design of Lars Johan Lehming. Today it is privately owned.

Before 1930 there was another building from the period when the noble family Wrangel owned the Castle.
Carl-Gustaf Wrangel was the owner from 1868 until 1872 and Helmuth Wrangel from 1872 until 1901. Ernst Linder was Rhen married with a daughter Wrangel. Owner between 1901 and 1905.
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.
