Antrim Castle was erected in stages between 1613 and 1662. It was destroyed by fire in 1922 and finally demolished in the 1970s. All that remain are a slightly raised grassed platform as well as a freestanding Italian stair tower which was built in 1887 and a gatehouse, which was built around 1818 with twin neo-Tudor towers, with older connecting walls.
The gardens, originally dating from the 17th-century, are a popular tourist attraction. Jacobean-Revival outbuildings of coursed rubble basalt with sandstone dressings were built about 1840. The entrance gateway to the demesne has octagonal turrets. The stable block was later converted for use as a family residence and renamed Clotworthy House. This was acquired by Antrim Borough Council and converted for use as an Arts Centre in 1992.
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.
