Explanation:

Lothal

• A different kind of town planning we found at Lothal; this city was divided into 6 sections and each section had a wide platform of earthen bricks. Lothal and Rangpur are two sites where historians found rice husk.
• The magnum opus of Lothal is an artifi cial dock. Lothal’s dock—the world’s earliest known, connected the city to an ancient course of the Sabarmati river on the trade route between Harappan cities in Sindh and the peninsula of Saurashtra when the surrounding Kutch desert of today was a part of the Arabian Sea.It was a vital and thriving trade centre in ancient times, with its trade of beads, gems and valuable ornaments reaching the far corners of West Asia and Africa.
• A bead making factory has also been found in Lothal. A seal from Iran has been found which indicates its link with overseas countries.
• Then, Lothal is different from other sites of Indus Valley Civilization in terms of town planning that it has entry to the houses on the main street while in other sites have shown lateral entry.
