Nave of Angers Cathedral, looking east. The nave dates from the mid-12th century. It has no side aisles and is composed of three large sections, each covered with a large ribbed vault that anticipates the Gothic style. The central crossing of the vaults are raised about 3 meters higher than the transverse arches, forming cupola-like tents over each bay. Each vault is a perfect square of 16.38m on a side. This unique style is known as the Angevin or Plantagenet vault. Hanging on the walls are the famous Angers tapestries, most of which date from the 14th century.
