Teaching at the university began in the chapterhouse of Glasgow Cathedral, subsequently moving to nearby Rottenrow, in a building known as the "Auld Pedagogy". The university was given of land belonging to the Black Friars (Dominicans) on High Street by Mary, Queen of Scots, in 1563. By the late 17th century its building centred on two courtyards surrounded by walled gardens, with a clock tower, which was one of the notable features of Glasgow's skyline—reaching in height—and a chapel adapted from the church of the former Dominican (Blackfriars) friary. Remnants of this Scottish Renaissance building, mainly parts of the main façade, were transferred to the Gilmorehill campus and renamed as the "Pearce Lodge", after Sir William Pearce, the shipbuilding magnate who funded its preservation. The Lion and Unicorn Staircase was also transferred from the old college site and is now attached to the Main Building.
