Päivääniemi in Lempäälä is an Iron Age burial ground consisting of around 130 small mounds. The ground was in use from 300 to 1000 AD, but most of findings date from 600-800 AD. The largest is so-called Kuninkaanhauta (King's Grave) where has been buried a local chief. The fine sword was founded from the grave in excavations.
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.
