Rawa Mazowiecka Castle is a Gothic style square formation castle located in the lowlands of the river Rawka and the river Rylka. Currently it is a renovated ruin.
According to the scriptures of Jan Długosz, the castle was built by Casimir III the Great, and the stronghold's function was to protect the southern borders of Masovia. Although reconstruction efforts have been raised by Franciszek Lanckoroński, the reconstruction was stopped, most likely due to the Partitions of Poland, after which the Prussian authorities ordered to deconstruct the ruins, only keeping the tower. The rest of the brick material was used for nearby housing. Currently the renovated tower is open to tourists, and the outline of the castle's former square formation has been reconstructed around the tower.
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.
