The pilgrimage church Maria Birnbaum and the former pilgrimage chapel and today's parish church Maria Loreto both in Upper Bavaria were built in the 17th century. However, their fates took very different courses thereafter. While Maria Birnbaum still serves as a pilgrimage church today and its Baroque furnishings have been preserved in their original form, the Loreto Chapel was rededicated as a parish church and fundamentally rebuilt in the 19th century. Both churches have centrally-located timber dome supporting structures, which became defective shortly after their completion. In the course of their maintenance history, various attempts were made to strengthen the structures. Nevertheless, the damage process continued in each case. It was only in recent years that the churches could be repaired sustainably from a structural point of view. The solutions implemented varied greatly. Both are convincing in their consistent application of the requirements of historic preservation regulations in the architectural and engineering interventions.      «
