Flag Staff Tower is located at a distance of 400 yards North of Cheuburg Mosque. Walk past the Chauburg mosque through ridge forest. Paths meet at flagstaff tower, built in (1828). Originally, a single tower on the highest point of the cantonment. The ridge had only shrubs in the early days and the signal could be seen far away. The building is in gothic style with castellated parapets. A part of the cantonment in style and in scheme. This would have remained just an ordinary watch and hunting tower if the 1857 Mutiny had not happened. The British women and children, survivors of the Delhi massacre - gathered here on the fateful day of May 11, 1857 before fleeing to Karnal. The tower stands tall on the highest part of the Northern Ridge just where Flag Staff Road intersects Magazine Road. Flagstaff Tower was one of the first substantial buildings to be constructed by the British on the Ridge. It was probably built when the army cantonment was moved in 1928.
