"There is sufficient proof of existence of a massive and monumental structure having a minimum dimension of 50 x 30 m in north-south and east-west directions respectively just below the disputed structure. In course of present excavations nearly 50 pillar bases with brickbat foundation, below calcrete blocks topped by sandstone blocks were found. The pillar bases exposed during the present excavation in northern and southern areas also give an idea of the length of the massive wall of the earlier construction with which they are associated and which might have been originally around 60 m (of which the 50 m length is available at present). The centre of the central chamber of the disputed structure falls just over the central point of the length of the massive wall of the preceding period which could not be excavated due to presence of Ram Lala at the spot in the make-shift structure [i.e., the makeshift temple erected after the demolition of the disputed structure]. This area is roughly 15 x 15 m on the raised platform. Towards east of this central point a circular depression with projection on the west, cut into the large sized brick pavement, signify the place where some important object was placed. ... The area below the disputed site thus remained a place for public use for a long time till the period VIII (Mughal level) when the disputed structure was built which was confined to a limited area ..."
