Houses in the lower town also contain similar altars.
Within the fortified citadel complex, the southern half contained many (five or six) raised platforms of mud bricks, mutually separated by corridors. Vandalism of these platforms by brick robbers makes it difficult to reconstruct the original shape of structures above them but unmistakable remnants of oval fire-pits of burnt bricks for have been found, with a Pali Peedam or sacrificial post (cylindrical or with rectangular cross-section, sometimes bricks were laid upon each other to construct such a post) in the middle of each pit and sacrificial terracotta cakes in all these fire-pits.The structure of these fire-altars is reminiscent of altars, but the analogy may be coincidental, and these altars are perhaps intended for some specific (perhaps religious) purpose by the community as a whole.In some fire-altars remnants of animals have been found, which suggest a possibility of animal-sacrifice.In this phase, the settlement was fortified, using dried mud bricks, from the beginning of occupation.This fort had been built twice in different periods.Toy carts suggest carts were used for transportation in early phase of Kalibangan. has also shown that there occurred an earthquake around 2600 BC, which brought to an end the Early Indus settlement at the site.".
KLB-I phase has left 1.6 meters of continuous deposits during five distinct structural strata, the last of which was destroyed perhaps by an earthquake and the site was abandoned around 2600 BCE, soon to be settled again by Harappans.
Some burnt wedge shaped bricks also have been found.
It has been found south east of the pre-Harappan settlement, outside the fort.
In fact, Tessitori is the first person to recognize that the ruins are 'Prehistoric' and pre-Mauryan. Traces of pre-Harappan culture have been found only at the lower levels of the western mound.
Luigi Pio Tessitori also pointed out the nature of the culture, but at that time it was not possible to guess that Indus Valley Civilisation lay in the ruins of Kalibangan, and he died five years before Harappan culture was duly recognized. According to archaeological evidence, the Indus Valley culture existed at the site from the proto-Harappan age (3500 BC - 2500 BC) to the Harappan age (2500 BC - 1750 BC).
The direction of houses and brick sizes was markedly different from that used in the Harappan phase (KLB-II).
