14 October 1973 is one of the most important dates in modern Thai history. Millions of pro-democracy protesters gathered at Ratchadamnoen Klang Road against the military dictatorship of Thanom Kittikachorn. The junta attacked the masses with snipers from rooftops killing dozens of civilians. Eventually the regime was toppled and Thailand became a constitutional monarchy. This memorial commemorates those who died that day, as well as those that died at similar protests in 1976 and 1992. You can read more about this hectic period in Thai history in the small museum.
