The festival, which kicked off last Sunday, featured light-and-sound shows plus a fair selling various fares and food.

Prasat Phanom Rung is an ancient complex and only a few times each year can one see the sun through all 15 doors of this castle during sunrise and sunset. For sunrise, the phenomenon usually runs from April 3 and 5, and again from September 8 to 10. Visitors can also witness the phenomenon during sunset between March 5 and 7, and October 5 and 7.

There is a widely held superstition that those who witness this amazing phenomenon at the Phanom Rung Castle will enjoy good luck.
