The Governor had directed to get the bunker opened after he was informed by old-timers three months ago about the presence of a tunnel inside the Raj Bhavan. On August 12, the staff of the Public Works Department at Raj Bhavan broke open a temporary wall that closed the entrance to the bunker on the eastern side, the official said in a statement. Instead of an underground tunnel, an entire barrack with 13 rooms of different sizes was found.

This tunnel is 150meter long 3meter wide and height is around 12 feet.
