St. Catherine’s Church was built for the Pärnu garrison in 1768 to replace the wooden church erected in 1752. It was named after Empress Catherine II, who travelled through Pärnu in 1764. As designed by architect P. Jegorov, St. Catherine’s Church is the one of the richest and most stylish examples of a baroque style in Estonia.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
