Excavated Lothal

On plan, Lothal stands 285 metres (935 ft) north-to-south and 228 metres (748 ft) east-to-west. At the height of its habitation, it covered a wider area since remains have been found 300 metres (1000 ft) south of the mound. Due to the fragile nature of unbaked bricks and frequent floods, the superstructures of all buildings have receded. Dwarfed walls, platforms, wells, drains, baths and paved floors are visible.[9] But thanks to the loam deposited by persistent floods, the dock walls were preserved beyond the great deluge (c. 1900 BCE). The absence of standing high walls is attributed to erosion and brick robbery. The ancient nullah, the inlet channel and riverbed have been similarly covered up. The flood-damaged peripheral wall of mud-bricks is visible near the warehouse area. The remnants of the north-south sewer are burnt bricks in the cesspool. Cubical blocks of the warehouse on a high platform are also visible.[9]
The ASI has covered the peripheral walls, the wharf and many houses of the early phase with earth to protect from natural phenomena, but the entire archaeological site is nevertheless facing grave concerns about necessary preservation. Salinity ingress and prolonged exposure to the rain and sun are gradually eating away the remains of the site. But there are no barricades to prevent the stream of visitors from trudging on the delicate brick and mud work. Stray dogs throng the mound unhindered. Heavy rain in the region has damaged the remains of the sun-dried mud brick constructions. Stagnant rain water has lathered the brick and mud work with layers of moss. Due to siltation, the dockyard’s draft has been reduced by 3–4 metres (10–13 ft) and saline deposits are decaying the bricks. Officials blame the salinity on capillary action and point out that cracks are emerging and foundations weakening even as restoration work slowly progresses.
