The Hanging Church gets its name from the fact that its floor was originally built across a gate of an ancient Roman fortress. The church contains a 10th-century icon of the Virgin and Child and an 11th-century pulpit constructed of 13 slender pillars, representing Christ and his apostles (the black pillar is said to represent Judas Iscariot). There are tour guides on-site who do not accept money in exchange for their tours, but instead suggest any tips be given as a donation to the church. Daily 9 am-5 pm. Free. Near the Mar Girgis Metro station (Old Cairo), Cairo.
