Lothal () was one of the southernmost sites of the ancient Indus Valley civilisation, located in the Bhal region of the Indian state of Gujarat. Construction of the city is believed to have begun around 2200 BCE.
Archaeological Survey of India (ASI), the official Indian government agency for preservation of ancient monuments, discovered Lothal in 1954. Excavation work in Lothal commenced on 13 February 1955 and continued till 19 May 1960. According to the ASI, arguably Lothal had the world's earliest known dock, which connected the city to an ancient course of the Sabarmati river on the trade route. This trade route stretched between Harappan cities in Sindh (Pakistan) and the peninsula of Saurashtra where the surrounding Kutch desert of today was a part of the Arabian Sea. However, this interpretation has been challenged by other archaeologists, who argue Khufu's Red Sea harbour at Wadi al-Jarf (Egypt) is older, dating its construction to between 2580 to 2550 BCE and that Lothal was a comparatively small town, and that the "dock" was primarily an irrigation tank.
The National Institute of Oceanography in Goa discovered foraminifera (marine microfossils) and salt, gypsum crystals in the rectangular structure clearly indicating that sea water once filled the structure and it was definitely a dockyard.
Lothal 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. The techniques and tools they pioneered for bead-making and in metallurgy have stood the test of time for over 4000 years.
Lothal is situated near the village of Saragwala in the Dholka Taluka of Ahmedabad district. It is six kilometres south-east of the Lothal-Bhurkhi railway station on the Ahmedabad-Bhavnagar railway line. It is also connected by all-weather roads to the cities of Ahmedabad (85 km/53 mi), Bhavnagar, Rajkot and Dholka. The nearest cities are Dholka and Bagodara. Resuming excavation in 1961, archaeologists unearthed trenches sunk on the northern, eastern and western flanks of the mound, bringing to light the inlet channels and nullah ("ravine", or "gully") connecting the dock with the river. The findings consist of a mound, a township, a marketplace, and the 'dock'. Adjacent to the excavated areas stands the Archaeological Museum, where some of the most prominent collections of Harappa-era antiquities in India are displayed.
The Lothal site was nominated, in April 2014, as a UNESCO World Heritage Site, and its application is pending on the tentative list of UNESCO.
Archaeology
When British India was partitioned in 1947, most Indus sites, including Mohenjo-daro and Harappa, became part of Pakistan. The Archaeological Survey of India undertook a new program of exploration, and excavation. Many sites were discovered across northwestern India. Between 1954 and 1958, more than 50 sites were excavated in the Kutch (notably Dholavira), and Saurashtra peninsulas, extending the limits of Harappan civilisation by to the river Kim, where the Bhagatrav site accesses the valley of the rivers Narmada and Tapti. Lothal stands from Mohenjo-daro, which is in Sindh.
The meaning of Lothal (a combination of Loth and (s) thal) in Gujarati is "the mound of the dead". This is not unusual, as the name of the city of Mohenjo-daro in Sindhi translates to the same. People in villages neighbouring to Lothal had known of the presence of an ancient town and human remains. As recently as 1850, boats could sail up to the mound. In 1942, timber was shipped from Broach to Saragwala via the mound. A silted creek connecting modern Bholad with Lothal and Saragwala represents the ancient flow channel of a river or creek.
Speculation suggests that owing to the comparatively small dimensions of the main city (), Lothal was not a large settlement at all, and its "dock" was perhaps an irrigation tank. However, the ASI and other contemporary archaeologists assert that the city was a part of a major river system on the trade route of the ancient peoples from Sindh to Saurashtra in Gujarat. Lothal provides with the largest collection of antiquities in the archaeology of modern India. It is essentially a single culture site—the Harappan culture in all its variances is evidenced. An indigenous micaceous Red Ware culture also existed, which is believed to be autochthonous and pre-Harappan. Two sub-periods of Harappan culture are distinguished: the same period (between 2400 and 1900 BCE) is identical to the exuberant culture of Harappa and Mohenjo-daro.
