Abraham Millauer built the Carmelite monastery in Reisach according to Johann Baptist Gunetzrhainer's plans. Until today it is seen as the jewel of the Inn valley. The foundation stone was laid in 1732, it was finished in 1746. The church was constructed in just two years from 1737 to 1739. After the secularisation in 1802 King Ludwig I approved the monastery could be rebuilt in 1835.
The monastery grounds and the tower with the beautiful domed roof in front of the mountain range is a familiar picture for many holidaymakers. The unusual interior design: a nave divided by pillars, semi-circle rounded narrow sides and a well-rounded barrel vault and the courtly genuine rococo interior characterise the church as an important sacral building from the 18th century in Bavaria. The altar piece and the paintings on the side altars were done by the Munich court painter Balthasar Albrecht, the four side altars were done by Johann Baptist Straub.
The monastery and the library can only be seen on a guided tour.
