8th April is ICOMOS International Day for Monuments and Sites but unofficially known as World Heritage Day.
This year Stonehenge and Avebury are celebrating 30 years of being a World Heritage Site along with six other sites, the first sites to be designated World Heritage Sites in the UK.
UNESCO established 18 April as the International Day for Monuments and Sites in 1983. It aims to raise public awareness about the diversity and vulnerability of the world’s built monuments and heritage sites and the efforts required to protect and conserve them.
