A protecting sign for
invaluable ancient relic or culturally invaluable building or
monument intended to protect against bombing etc. The
ideogram is called Roerich sign after its creator. It was introduced after
international conferences held during the 1930s. It has, however,
seldom been used, as witness the enormous devastations of culturally
invaluable buildings by bombing during World War II.
The structure is the same as that of a sign worn by deaf persons to protect them in traffic.
Compare with in Group 8 with a similar meaning.
