St Andrews Cathedral is a fascinating historical site in Scotland that was once the hub of the Medieval Catholic Church. Built in 1158, this magnificent cathedral housed the relics of St Andrew and served as a center of worship until it fell into ruin during the 16th-century Scottish Reformation. With its grandeur slowly fading over time, the cathedral became a source of building materials for the town after a Protestant mob attack in 1559, led by the fiery preacher John Knox. Despite its current state of decay, St Andrews Cathedral stands as a captivating reminder of Scotland's rich religious past, offering visitors a glimpse into centuries-old architecture and the tales of saints and kings.
