A local rendition of Paris' Arc de Triomphe. Besides the elaborate Buddhist embellishment, it differs from the original in having four gates instead of two and being just a bit higher (to spite the French). Reasonably impressive from afar, a surprisingly frank English sign inside the monument labels it a "monster of concrete" when seen up close - and the concrete in question was donated by the US, although it was supposed to go towards a new airport instead. The monument itself aside, the palm tree-lined park around it complete with fountains is quite pleasant, and you can climb up to the 7th story (stairs only) for a view of downtown Vientiane.
