Vientiane

"Vientiane": Originally the name would be "Vienkham" ("Golden Gate" or rather "Golden Wall"), so called because in ancient times a king of Laos who was siege of this city named her so. The protections of the city - bamboo spikes stuck in the ground - were so important and so numerous that the soldiers could not cross them. He ordered his archers to smear the tips of their arrows with gold, and fire in these bamboo shields for three days, then he rang the retreat. Suddenly the inhabitants left the city and cut the spades to go get the gold, the city was thus vulnerable (it reminds you something ...?). The king who waited in ambush then seized the city and named it "Vienkham", ie "city with golden walls", which later became "Vientiane".
