You might want to read this news item about the world tour of some relics of the Buddha.
When I was in Taiwan in May a world tour of Buddha's relics had recently been there. They had been successively enshrined in a number of temples during the celebrations called Wesak. (This marks the start of the Buddhist new year during which the Buddha's Birth is celebrated). By all accounts this was a huge event with thousands of people walking past and paying their respects.
In July, back in the UK, I was taken to see some Relics in a temple in Birmingham. In a posting on July 15th I ponder on the issue of authenticity of such relics. Like the ones in the news item these were quite low key in their public presence yet non the less 'present' in an intangible sense.
