The renovation was completed on 8 December 2002 and cost a total of US$1.1 million. The project's success in preserving the building's heritage resulted in the cathedral being given an honourable mention at the 2003 UNESCO Asia Pacific Heritage Awards for Culture Heritage Conservation and presented with the award on its anniversary in 2003.
