Siida is home to the Sámi Museum and Northern Lapland Nature Centre. Siida arranges exhibitions on Sámi culture and the nature of Northern Lapland. In addition, Siida has an open-air museum open in the summers, which was originally known as the Inari Sámi Museum. The first buildings were moved to the museum grounds in 1960. The 7-hectare (17-acre) area has nearly 50 sites of interest related to Lapland's nature and the Sámi and their culture. Furthermore, the area is where the earliest settlers in Northern Lapland lived and archaeological finds from approximately 9,000 years ago have been found.
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.
