Ulm cathedral has double aisles and a pentagonal apsidal choir, but no transepts.
The main room of the ordinary temple was rectangular, with an elevated apsidal arrangement, like a choir, containing the sacred relief on its wall, at the end opposite the entrance, and with continuous benches (podia) of masonry, about 5 ft.
The plan is unusual, consisting of a large nave without aisles, the span being between 45 and 50 ft.; it also has two shallow transepts and an apsidal east end.
Sainte-Marie contains many artistic treasures, the chief of which are the magnificent stained-glass windows of the Renaissance which light the apsidal chapels, and the 113 choir-stalls of carved oak, also of Renaissance workmanship. The archbishop's palace adjoins the cathedral; it is a building of the 18th century with a Romanesque hall and a tower of the r4th century.
The transepts have eastern apsidal chapels, as have the choir aisles, though the walls of these last.
