The other type of main hall architecture is the narrower rectangular plan with high arched ceiling type chaitya-griha – literally, "the house of stupa". This hall is longitudinally divided into a nave and two narrower side aisles separated by a symmetrical row of pillars, with a stupa in the apse. The stupa is surrounded by pillars and concentric walking space for circumambulation. Some of the caves have elaborate carved entrances, some with large windows over the door to admit light. There is often a colonnaded porch or verandah, with another space inside the doors running the width of the cave. The oldest worship halls at Ajanta were built in the 2nd to 1st century BCE, the newest ones in the late 5th century CE, and the architecture of both resembles the architecture of a Christian church, but without the crossing or chapel chevette. The Ajanta Caves follow the Cathedral-style architecture found in still older rock-cut cave carvings of ancient India, such as the Lomas Rishi Cave of the Ajivikas near Gaya in Bihar dated to the 3rd century BCE. These chaitya-griha are called worship or prayer halls.
