two. The fortification wall of the citadel has an average base width of and has two bastions on the southern wall. Similar bastions are expected on the northern wall but have not been excavated yet. On the southern wall of the citadel there is a centrally placed gateway projecting out. This gateway measure and has steps and a ramp leading up to the main entrance which has two guard rooms. There is a wide passage leading into the entrance. The citadel consists of large houses some of which have up to nine rooms each. From the citadel there is an entrance in the east wall, again wide, for access to the residential complex. The residential area consists of houses which are the smaller than the citadel houses. A typical example is a house with five interconnected rooms, a courtyard closed on three sides and a platform outside facing the street. The platform would have been used for transactions and as a shop. The southern fortification wall of the residential area also has an entrance which has received a different treatment by its builders. It differs from other Harappan gates in the sense that it is a straight entrance and not a staggered or bent one. The gate itself is set in the thickness of the fortification wall while there are two guard rooms projecting out. The fortification wall of the residential complex has an average thickness of and has bastions at the corners which are smaller than the ones on the citadel fortification wall. All these features show mature Harappan traits even up to 1700 BC which chronologically is quite remarkable. Mature Harappan principles were being followed in Surkotada long after the civilization itself had started declining and most other sites had decayed or died out. As of today there is no evidence of a city scale settlement near the citadel complex of Surkotada, as one might be expected on the lines of Mohenjo-daro and Kalibangan. About south-east of the citadel, there is a low mound which represents some sort of small habitation but the Harappan vestiges are scarce. Archaeologists feel that the possibility of the existence of a large settlement is remote but cannot be ruled out. Horse remains During 1974, the Archaeological Survey of India undertook excavations in this site. J.P.Joshi and A.K.Sharma reported findings of bones at all levels (circa 2100-1700 BCE), which they described as horse
