Image Source: IANS News Chandigarh, July 16 : Historical tunnel-like structures were unearthed while excavating the basement of a building in the complex of the holiest of Sikh shrines Harmandir Sahib, popularly known as the Golden Temple, in Amritsar, officials said on Friday. Several Sikh bodies have been demanding the construction at the site be stopped and authorities should focus on restoring the structures as the brick-lined structures hold religious significance. The tunnel-like structures made of small bricks, believed to be used centuries ago, were found at a depth of 25 feet during the construction of a 'jora ghar' (shoe rack) on Thursday.
