Großriedenthal has always been connected to Melk Abbey via the original parish of Ravelsbach. The oldest record of the existence of the parish dates back to 1265, when it was probably already a parish in its own right. The church at that time was probably a small stone church. Parts of today's tower could still be from this church.
The present church was built in 1768 according to the designs of the Viennese master builder Josef Gerl. The main altar features a painting of the church's patron saint, St. Lawrence, signed by Martin Johann Schmidt, the so-called Kremser Schmidt, in 1769. Lorenz.
