A Spanish court sentenced a man on Wednesday to 10 years in prison for crimes including the theft of a priceless medieval document considered the first guidebook to Spain's Saint James pilgrimage trail.

Police recovered the unique 12th-century manuscript in July 2012, a year after it was found to have gone missing from a safe in the famous cathedral of the northwestern city of Santiago de Compostela.

Judges in a court in the nearby city of La Coruna said in a written ruling that they "consider it proven" that an electrician who worked for years at the cathedral, Manuel Fernandez Castineiras, stole the manuscript.
