N • The area of city during the period 1411-1770 was 5.3 sq.km. • The establishment of the first textile mill in 1861 was a landmark. With expansion of this industry, development began to spill over (beyond city walls) towards the north-east & south-east of walled city, but only on the Eastern side of the river. • Construction of Ellis Bridge in 19th century opened up the Western side for urban expansion – mainly Residential. • Industrial development – Eastern side. • Commercial development – Walled City. • City extended beyond present municipal limits & crossed limits of AUDA on Western side. • After 1982 growth was observed on main transportation routes, where agriculture was predominant.
