With the 11-acre complex painstakingly restored over a period of four years, the government now also seeks to expand the World Heritage Site zone to include this restored complex.
"April 18 was declared as a World Heritage Day in 1983 by UNESCO and the day serves to bring to focus the diversity and vulnerability of monuments and built heritage sites, not just in Delhi or India but around the world," Secretary of Ministry of Culture Ravindra Singh said.
"The site forms important part of the 16th century necropolis adjacent to the dargah (shrine) of 14th century Sufi saint Nizamuddin Auliya.
"There are 29 monuments in the (Nizamuddin) area, and dargah's presence here is the central...The three tombs present at the restored site here are of national importance...And, this year we will seek to include this (Batashewala complex) within the extended World Heritage Site zone," he said.
