Less than 100 years later, early in the subsequent dynasty, pharaoh Senusret I replaced Mentuhotep's structure with a totally new temple and courtyard.[6] While all earlier building follow the same layout and exclusively used mud bricks, the new temple was entirely made in limestone. By this time, the level of the temple was above the rock niche of the Old Kingdom. However, the main sanctuary was built directly over the old one, therefore keeping the old tradition.
