Segovia

Burgos, founded in the 9th C. (the Celtic-Iberian era) is home of the Cathedral of Burgos, consideredone of the best examples of a Gothic cathedral. History is the main reason for coming here - the sheer beauty of a graceful medieval town is everywhere

El Espolon Boulevard, the center of town, is a great place to start exploring Burgos with kids. While strolling around the city, a great place to stop for a snack is around the Cathedral, where you'll find a cluster of tapas cafes.
The Burgos Cathedral in the Plaza Santa Maria is a treasure of Gothic architecture begun in 1221. Besides the sheer beauty of the architecture, the Cathedral is worth visiting for its art (including medieval paintings, sculptures, goldsmith and silversmith pieces, tapestries, and a 16th century Bible) and the tomb of El Cid, the legendary Burgos hero.
