Editing Lothal (section)

===Town planning===
A flood destroyed village foundations and settlements ({{Circa|2350&nbsp;BCE}}). Harappans based around Lothal and from Sindh took this opportunity to expand their settlement and create a planned township on the lines of greater cities in the Indus valley.<ref name="Rao10">{{cite book

}}</ref> Lothal planners engaged themselves to protect the area from consistent floods. The town was divided into blocks of 1- 2m high (3–6&nbsp;ft) platforms of sun-dried bricks, each serving 20–30 houses of thick mud and brick walls. The city was divided into a [[citadel]], or [[acropolis]] and a lower town. The rulers of the town lived in the acropolis, which featured houses with paved bathing platforms, underground and surface drains (built of kiln-fired bricks) and potable water well. The acropolis also housed the towns warehouse, with a ramp down to the basin, on the towns eastern flank. The lower town was subdivided into two sectors. A north–south arterial street was the main commercial area. It was flanked by shops of rich and ordinary merchants and craftsmen. The residential area was located to either side of the marketplace. The lower town was also periodically enlarged during Lothal's years of prosperity.{{citation needed|date=May 2015}}

All the construction were made of fire dried bricks, lime and sand mortar and not by sun-dried bricks as bricks are still intact after 4000 years and still bonded together with each other with the mortar bond.<ref>{{Cite web |url=http://static.panoramio.com/photos/large/78538322.jpg |title=Archived copy |access-date=25 April 2014 |archive-date=1 February 2018 |archive-url=https://web.archive.org/web/20180201193030/http://static.panoramio.com/photos/large/78538322.jpg |url-status=dead }}</ref>
