Say you’re a country with a beautiful temple, and you want to register it as a World Heritage Site. Say your neighbor claims the land surrounding your temple.

When you’re one of two countries involved in this, you go to UNESCO to help patch things up. Same with Thailand and Cambodia: the Preah Vihear temple building lies in Cambodian territory, but can only be easily accessible through Si Sa Ket province in Thailand.

This is a hopeful chapter in a long history of dispute over Preah Vihear. The trouble began in 1904, when Siam (as Thailand was known then) ceded territory to the French colonizers in charge of Cambodia. Preah Vihear has served as a political chesspiece since then; the last flare-up happened in 2002 over garbage thrown carelessly by Cambodian vendors in the vicinity.

You may want to pencil in Preah Vihear for a later date, but you might still want to see what other temples Southeast Asia has to offer in our list of the region’s sacred sites.
