St Cadwaladr's Church is a Grade I listed church in Llangadwaladr, Anglesey. The church is built in the perpendicular style. The nave is dated to the 12th to early 13th century and the chancel to the 14th. Considerable additions were later made in the mid 17th century, with the north chapel in 1640 and the south chapel in 1661. In 1856 the church underwent restoration, at which time to south porch was added.
In the newer part of the churchyard, south of the church, are war graves of four British airmen and a Polish airman of World War II.
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.
