The Church of the Holy Spirit (German: Heiliggeistkirche) is the most famous church in Heidelberg, Germany. It stands in the middle of the market place in the old center of Heidelberg not far from the Heidelberg Castle. The steeple of the church, rising above the roofs, dominates the town.
The Church of the Holy Spirit is first mentioned in a manuscript from 1239. In 1398, the foundations of the current late Gothic church were laid on the site of a late Romanesque basilica which, in turn, had been erected in the place of an even older church. Thus the current church is the third sacral building on the site.
Documents name Arnold Rype, who was also mayor of Heidelberg for a time, as the master builder. In the usage of the time, the term "master builder" referred not to the architect but the financial coordinator. The only known architects during the church's construction are Hans Marx, who worked on the church until 1426, as well as Jorg, who was responsible until 1439. Both men probably supervised work on the nave. Under the reign of Prince-elector Frederick I a noted specialist in the construction of church towers, Niclaus Eseler, came from Mainz to Heidelberg and was probably responsible for the execution of the primary work on the spire of the Church of the Holy Spirit. Nevertheless, the steeple was completed by Lorenz Lechler.
The construction lasted for some one hundred and fifty years. The Choir was consecrated in 1411 and the nave was finished in 1441. Probably in the same year the construction of the steeple was started. The work was interrupted until 1508 and the tower was finished in 1544. In 1709, after the church had been set on fire by the French during the War of the Palatinian Succession, it was rebuilt and received a baroque spire.
In the 14th century, the Church of the Holy Spirit took over as parish church from St. Peter's Church, which became the university church for the University of Heidelberg.
