The Bishop's Castle (also known as Glasgow Castle, the Bishop's Palace, and the Archbishop's Palace) was a medieval castle in Glasgow, Scotland. It stood to the west of Glasgow Cathedral, covering much of the present day Cathedral Square. The castle served as the residence of the Archbishops of Glasgow until 1689.[1] Following the Glorious Revolution, the castle became the property of the Crown. It fell into disrepair during the 18th century, having been used as a quarry from 1755, and the site was cleared in 1789 to make way for the Glasgow Royal Infirmary.
