The International Day for Monuments and Sites (informally known as the World Heritage Day) was created on 18 April, 1982, by the International Council on Monuments and Sites (ICOMOS) and later approved at the 22nd UNESCO General Conference in 1983.

The theme of the meeting this year is Heritage and Science.
