Origins
Until the 9th century, the city of Santiago did not exist as such. However, archaeological excavations have shown that the present-day location of the old town was the site, in antiquity, of a Roman town that acquired certain importance and remained until the 7th century, forming part of the Swabian kingdom during some time. In the 1st century, alongside the walled enclosure of the Roman “civitas”, a pagan mausoleum was erected that subsequently gave rise to the cathedral. It has been demonstrated that, in that same century, three Christian martyrs were buried in the mausoleum, which became an established centre of worship, as shown by the nearby Christian cemetery that was used until the 7th century.
