 A ramp was also built to enable site access for the necessary heavy construction vehicles.Prior to work commencing, a traditional ceremony was performed to restore the sanctity of the site, which had served a dual role as both a physical tomb and spiritual link to venerated ancestors.Estimated initial reconstruction costs were put at 20 million U.S. dollars by experts from UNESCO, which was the principal contributor of funds as well as expertise due to the Rova's then status as a soon-to-be officially recognised World Heritage Site.
