The Catholic church was built in the early 18th century by Prince Paul Esterhazy, and Eisenstadt was the seat of the Esterhazy family. The church is located a short walk west of the family's main palace. This church is characterized by an unusual architectural style and is built in two parts, and is distinguished from the inside by its beautiful Baroque character. This church is famous for its ancient musical history, where many musical performances are organized, including the performances of Joseph Haydn, a composer in the classical period, which made it the incubator for the tomb of this wonderful musician.
