A presumable mistake in CPMP model was noticed. There were doubts if the CPMP model was entirely correct - the interior walls with painted rosettes are visible on some sources and on the others the walls are missing. A careful comparison of the sources, also from the New Synagogue in Hannover, was performed. The final conclusion was that the walls were added in the later projects and has no analogy in the Synagogue in Hannover. The model had to be corrected and new walls had to be added (between the main nave and the side aisles and between the transept and the side aisles).
