Experts concluded that the structure that was revealed in the Hosakerehalli lake in Bangalore, India, dates in fact back to 1000 AD.
The structure was revealed by workers removing silt and weeds from the lake about a month ago. It resembled a mandapa, a pillared outdoor hall, but was actually a sluice gate belonging to the Chola dynasty (300 BC-1279 CE). The initially estimated age of 400 years was in fact declared to 1000 years. The structure measures a height of 4.5 metres and width of 2.5 metres. It has four pillars and a roof. Workers dug around 3 metres deep to unearth the entire structure. During the desilting process, another historical structure at the site was dismantled by an earthmover. The lake was built to provide drinking water as well as for agriculture. It was a popular fishing spot at one point of time. Due to rapid urbanisation, people started dumping garbage in the lake and it gradually became polluted to the extent that the structures in it became invisible.
