Glasgow Cathedral has a habit of losing things: a splinter of the true cross, the bones of several saints, and allegedly a vial of the Virgin Mary's breastmilk, all vanished without explanation.

Built between the 13th and 15th centuries, it survived the Reformation intact, though the tomb of St Mungo, the city's patron saint, was smashed up in its lower church in 1559. A darker legend tells of a boy sent into a tunnel beneath it with his dog and bagpipes, his tune tracked from above until it stopped abruptly. The dog reappeared days later, starving and hairless. The boy never did.

Bishop William Turnbull founded the University of Glasgow here in 1451. VoiceMap's audio tours trace these threads through the city: one explores the cathedral's stonework and saints, another follows its ghost stories to the Necropolis, and a third links it to the university it once housed.
