Château de Brax was originally constructed in the 13th century, but there were alterations and additions in the 16th and 18th centuries. The structure is enclosed by four circular towers. The rear façade incorporates the grand staircase. The brick walls are crenellated. The front opens onto parkland; access is by a double staircase. A round walk carried on machicolations formed of brick corbels and blind arcades circles the whole building.
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.
