One of the biggest events to commemorate Khao Phansa Day in October - the end of Buddhist Lent – is the Sakhon Nakhon Wax Palace Festival. It’s an outstanding example of Thailand’s many inspirational Buddhist holidays, and one of its most picturesque. The local people use beeswax to create moulded Buddhist temples, shrines and other imposing wax castles. All these artistic talents from around this northeastern province bring their wax castles to be proudly displayed in a grand procession. There are also boat races and other cultural performances, that showcase rural cultural and the spirit of the people of Sakon Nakhon.
