When I was strolling from the faculty library to the central library, the belfry was playing. Every Wednesday during lunch hour sweet tunes emerge from the tower. Not your some unknown music, but the musician manipulating the bells adapts contemporary pop songs. Yesterday, during my brisk walk, I heard 'Killing me softly' by The Fugees and an excellent 'Nothing else matters' by Metallica.
The library is absolutely dead silent (except on market days), but when the big bell is struck you can feel the sound going through the whole building.
