The oldest parts of the Ekeby Church date back to the 12th century, with subsequent expansions over the years. In the mid-17th century, the church's eastern gable was restored and a brick chancel was added, becoming a burial chapel for the Ribbing family. The church tower was added between 1752 and 1754 at the request of Pastor Curman, replacing the old bell tower. The central stone pillars and vault were removed in 1786, replaced by a wooden vault. In 1846, a new oak cross was added to the church tower, gilded with gold by mirror manufacturer Stenberg in Vadstena, based on drawings possibly by architect Carl Hårleman.
The pulpit, made of oak, pine, and hardwood, was crafted in the 17th century and donated in 1675 by Erik Ribbing and Beata Rosenhane. The triumphant crucifix is likely from the 14th century. Madonna sculpture in carved and painted wood, was probably from a local workshop in the 15th century. Sandstone baptismal font dates from the 12th century, featuring carved figures of two bishops, a layman with a lily, and a woman with an apple.
Altarpiece depicting Christ on the cross surrounded by Virgin Mary, Mary Magdalene, and John, painted in 1693 by David Klöcker Ehrenstrahl and donated by Catharina Ribbing in 1697.
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.
