Alderney Society Museum, the principal museum in Alderney, is located in the Old School House. Exhibits there fully reflect the history of the town and include a collection of rare maps, a list of British Regiments stationed in Alderney starting with 1732, old records, the 1940 Census of Alderney, finds of the Elizabethan shipwreck, and many rare artefacts. The museum is administered by the Alderney Society, which established it in 1966 with the purpose of creating 'an organisation dedicated to the historical, environmental and scientific promotion of the Island of Alderney'.
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.
