This Large, Art Deco monument-four hightly stylised angel wings arranged in a circle at the intersection of Th Ratchadamnoen Klang, Th Din So and Th Prachatipatai-was erected in 1932 to commemorate Thailand's momentous transformation from absolute to constitutional monarchy. Italian artist Corrado Feroci designed the monument and buried 75 cannonballs in its base to signify the year BE475 (AD 1932). Before immigrating to Thailand to become the nation's "father of modern art", Feroci designed monuments for Italian dictator Benito Mussolini.
In recent years "Th Demo" has become a favourite spot for public demonstrations, most notably during the antimilitary, prodemocratic protests of 1992.
