The present Endre church was preceded by an older, Romanesque church. Of this church, only the tower, built in the 12th century, remains. A few stone sculptures have also been re-used in the later church, e.g. one sculpture depicting a dragon and another a lion. These are now immured in the southern façade of the church. The rest of the church dates from the 13th century (the choir and sacristy) and the early 14th (the nave). The building material of the church is limestone.
Apart from the aforementioned Romanesque sculptures, the exterior of the church is also adorned with sculpted portals, both Romanesque and Gothic in style.
Internally, the church is decorated with frescos made by the artist known as the Master of the Passion of Christ in the middle of the 15th century. The frescos were uncovered during a renovation in 1915. The church also have several preserved stained glass window panes from the Middle Ages. The altarpiece is furthermore medieval, from the late 14th century, as is a preserved church tabernacle. The triumphal cross dates from circa 1300, and the baptismal font, possibly made by the artist Hegvald, is a Romanesque piece from the 12th century, richly decorated.
The church lies in a cemetery that is surrounded by a low limestone wall, in which a medieval lychgate still survives.
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.
