Thrissur is located in "Gods Own Country - Kerala" in India. It is the land of festivals and celebrations. Thrissur Pooram is a world famous event which usually happens in April/May every year. See http://en.wikipedia.org/wiki/Thrissur_Pooram
for more details
I could not cover the whole event, but could get a few night shots, temple decorations & preparation for the Pooram.
