Holy Smokes! Now THAT'S a THURIBLE!

You want incense? You got incense! This is the "Botafumeiro (Smoke Boat)" in the Santiago de Compostela Cathedral, Galicia, Spain. The cathedral is the supposed burial location of St. James the Great.

This little tidbit made me laugh (from Wikipedia):

"One of the most renowned accidents took place during a visit of Princess Catherine of Aragon. She was on a journey to marry the heir to the English throne in 1499 and stopped by the cathedral in Santiago de Compostela. While it was being swung, the Botafumeiro flew out of the cathedral through the Platerias high window. No one was reported to have been injured on this occasion."
