The Elephant's Rock is a large boulder of trachyte and andesite, eroded by the atmospheric agents that gave it the shape of an elephant. It is about 4 meters high. The rock is located near Castelsardo, to the left of the old road that led from the hamlet of Multeddu to the village of Sedini.
The Elephant's Rock has a great archaeological importance, because two domus de janas, ancient tombs dating back to the pre-nuragic period, have been carved inside.
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.
