"The awareness of beauty will save the world”
"Where there is peace, there is culture
Where there is culture, there is peace."
(Nicholas Roerich - Nikolai Rerikh - Николай Константинович Рерих, 1874-1947)

The Banner of Peace is a powerful universal symbol which was adapted by the visionary artist Nicholas Roerich to serve as an emblem for the desire of human culture to rise above war. This flag has been flown globally, as a sign of peace and culture, since the 1930's.

The circle that surrounds the three spheres represents culture, the unity of art, science, and spirituality.
