KATHMANDU: The Department of Archaeology (DoA) has estimated that the reconstruction of the Dharahara landmark would cost Rs 2.80 billion. A research report on the reconstruction of the landmark shows that its location will be spread over 42 ropanis of land with the tower itself standing 245 feet. There will be a garden and an underground parking for the visitors. The Department's Director General Bhesh Narayan Dahal said the report will be presented to the Nepal Telecom within a week. The Telecom will build the tower based on the report. The centuries-old historic monument had collapsed in the devastating earthquake on April 25, 2015.
