In contrast to Oberleutasch, no church existed in Unterleutasch prior to the 19th century. The inhabitants of Unterleutasch frequented the parish of Mittenwald to which, from the church’s point of view, they had always belonged. It was only in 1803, that by high decree of Emperor Franz II, permission was given to build a church. However, due to the war of 1805 and the subsequent subjugation to Bavaria, the building plans could not be carried out. Only in mid 1827,  the court chancellery issued a new decree allowing the church’s construction, with building finally commencing at the end of the same year. Under the supervision of the Mayor and Director of Construction, Matthias Reindl, and the Highway Surveyor, Johann von Klebelsberg, who most likely also drew up the plans, Josef Waldhart of Imst built the church and the vicarage, completing it in 1829. He built a simple nave with an inset directly adjoining the choir. Both sections of the building have hipped roofs with a tower rising from the western part. In 1955, a porch was added from which one steps into the interior through a circular area, the former baptistery, and the organ loft within the first bay. This
