Aruküla manor (Arroküll) evolved into an independent estate in the 17th century. The manor house seen today was built in 1782-1789, but suffered damage in a fire around 1800 and was subsequently rebuilt in a typical St. Petersburg-style Neoclassicism, with details such as decorative stucco laurel wreaths and a wrought-iron fence surrounding the manor park.
Russian general Karl Wilhelm von Toll, mentioned by Tolstoy in his epic "War and Peace", lived on Aruküla manor and is buried in a chapel on the grounds.
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.
