The Old Main bell joined a cacophony of bells tolling 150 times on Feb. 10, 2009, in celebration of  Boulder’s sesquicentennial anniversary.

For decades the Old Main bell rang between class periods and for home football victories. After a wild night of celebratory ringing following a win over the Colorado School of Mines in 1926, the bell cracked. As a result it was moved to the men’s gymnasium. In 1948, brawny Mines students stole the 1,000-pound bell. Its whereabouts remained a mystery for two years until Mines staff unearthed the bell with a giant “M” carved into its side.

After sitting in Macky Auditorium (see photo), it found a permanent home in the newly opened ���������� Heritage Center in 1985.
