The Basilica of St. James and St. Agnes is a basilica minor in Nysa. It is the largest sacramental building in the town, and historically cultural site of the town. The basilica was built on the turning point of the twelfth and thirteenth centuries, in the area known as the New Town. It was the first parish church, raised in between 1195 and 1198, consecrated by Wrocław's Jarosław Bishop in 1198.
The current church was built in two phases. The first stage was built before 1392, when the six-span church was built. The second stage was built between 1424 and 1430, when the chancel and ambulatory were built. St. James's Church was the highest building in the town at that time, with its rooftop surpassing all of the town's structures; taking part in an exceptionally historic part of town.
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.
