where has a sea-port of the harappan civilization been discovered
Lothal Lothal (IPA: [loˑt̪ʰəl]) is one of the southernmost cities of the ancient Indus valley civilization,[1] located in the Bhāl region of the modern state of Gujarāt and first inhabited c. 3700 BCE.[2] Discovered in 1954, Lothal was excavated from 13 February 1955 to 19 May 1960 by the Archaeological Survey of India (ASI), the official Indian government agency for the preservation of ancient monuments. According to the ASI, Lothal had the world's earliest known dock, which 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. However, this interpretation has been challenged by other archaeologists, who argue that Lothal was a comparatively small town, and that the "dock" was actually an irrigation tank.[3]
Mohenjo-daro Mohenjo-daro (Sindhi: موئن جو دڙو‎, Urdu: موئن جو دڑو‎‎, IPA: [muˑənⁱ dʑoˑ d̪əɽoˑ], Sindhi for Mound of the Dead Men;[2] English: /moʊˌhɛn.dʒoʊ ˈdɑː.roʊ/) is an archaeological site in the province of Sindh, Pakistan. Built around 2500 BCE, it was one of the largest settlements of the ancient Indus Valley civilization, and one of the world's earliest major cities, contemporaneous with the civilizations of ancient Egypt, Mesopotamia, Minoan Crete, and Norte Chico. Mohenjo-daro was abandoned in the 19th century BCE as the Indus Valley Civilization declined, and the site was not rediscovered until the 1920s. Significant excavation has since been conducted at the site of the city, which was designated an UNESCO World Heritage Site in 1980.[3] The site is currently threatened by erosion and improper restoration.[4]
