SAS NAGAR, also known as Mohali is a suburb of Chandigarh, 18th District in Punjab, India. It is officially named after the eldest son of Guru Gobind Singh, Sahibzada Ajit Singh (SAS Nagar). Mohali was conceived as an industrial township in late 1960s and early 1970s. It is said that residential areas were hurriedly conceived and constructed near the village of Mohali in Punjab (the first village on the main road link from Chandigarh UT to Punjab) - for accommodating the delegates of the 1975 All India Congress Session held at Chandigarh. Today, Mohali and Chandigarh are contigious areas with only the boundary of Punjab and UT of Chandigarh dividing this area.
