History
According to the Roman Christian poet Prudentius, San Emeterio and San Celedonio, two Roman brothers and legionaries who converted to Christianity, were beheaded in Calahorra around the year 300.[2] Local legend states that the cathedral was built on the spot where the two were killed.[3] They are now venerated as patron saints of the city and their relics are still kept inside the cathedral.[3]
Construction of the current building began in 1484[6] in the Gothic style, but gained several other influences over the next centuries, the facade and interior decorations being examples of Baroque.[7] The main work on the cathedral was done by the 18th Century, with the last element added being the retable of the main altar, in 1904,[8] after the original one was destroyed during a fire in 1900.[9]
