The oldest building lies to the west end, but is sandwiched between other larger buildings and easily missed. It stands on the south side of the street, just west of where George IV Bridge crosses over the Cowgate. This is the Magdalen Chapel, a 16th-century almshouse chapel built with monies left by Michael MacQueen in 1537. Work was completed in 1544 and it operated as a hospital almshouse (dedicated to Mary Magdalen) under the control of MacQueen's widow, Janet Rynd until her death in 1553, when it passed to the Incorporation of Hammermen (metalworkers). The entrance as seen from the Cowgate was rebuilt in 1613. The spire was added in 1620.
