Burgos is a big city of population 175,000. It is also home to the 13th century Catedral de Santa María, one of the largest in Spain. We had the chance to tour the building and it was pretty amazing. They had little hand held speaking devices that gave you the history of the parts inside in whatever language you wanted. We were there for only 1 day and only scratched the surface of what the city had to offer but the Tour was worth it.
