Class 107 was a classroom located in the South Tower of Hogwarts Castle. Sometime during the 1990s, a sign-up sheet for a trip to Hogsmeade on Saturday the 15th of an unknown month was posted on the noticeboard in Gryffindor Tower (and presumably in the common rooms of the other houses as well), and students who registered for it were instructed to meet at 10am in this classroom.[1]
