According to a stone plaque there, many nations contributed to the restoration fund and I am proud to say, Singapore contributed too. I think we paid for one of the toilets in the visitor centre.
We climbed the three terraces to the top as Roy, our guide told us the stories behind the temple panels which illustrated the story of Prince Siddharta Gautama's path to becoming The Great Buddha Sakyamuni. I cannot imagine the painstaking work that must have gone into each panel to tell that story.
We, the modern man, take so much for granted. We have Powerpoint slides with tacky canned art to use these days. They only had rock and chisel.
Maybe that's why the work of ancient craftsmen stood the test of time and became one of the Wonders of the World, while we delete our Powerpoint slides after a day at a presentation.
