Situated around the town of St Andrews are cobblestone markings denoting where Protestant martyrs were burnt at the stake. To students, the most notable of these is the cobblestone initials "PH" located outside the main gate of St Salvators College (part of the University of St. Andrews). These cobblestones denote where Patrick Hamilton was martyred in 1528. According to student tradition, stepping on the "PH" will cause a student to become cursed, with the effect that the offender will fail his or her degree and so students are known to jump over the cobblestones when passing.
