 Evaluation of the importance of the elements involved and the decision as to what may be destroyed cannot rest solely on the individual in charge of the work.Saint Laurentius church was proven to be one of the few preserved Ottonian buildings of the region and it was decided to restore the traces of its original structure and integrate the missing elements following thorough research and comparison with similar buildings of the same period.Each integration was made with recognizable materials, using non-permanent techniques to facilitate the removal in case of future restorations.
