A single apartment sits at the top of an ancient tower in the middle of the Jordanian desert. The tower at Um er-Rasas stands 46-feet-tall with no door, no stairs, and no way to ever leave. The square base of the tower, one mile north of the Byzantine city of Kastron Mefa’a is completely solid and constructed so well it still stands after 1,000 years of desert wind and sun. The church and courtyard at its base have crumbled into dust.

Now home to only birds, the tower may be the only standing structure left from the Stylite movement. These ascetic, Christian monks were so dedicated to self-discipline and depriving themselves of comfort they lived in isolation high above the rest of the world. The Jordanian tower likely housed one of these Stylite monks in the fifth-century.

The Stylites followed the footsteps of St. Simeon Stylite the Elder. Known for his unceasing prayer, Simeon became so popular to pilgrims he had no time for his own devotions. To guarantee he had quiet, Simeon climbed aboard a platform on the top of a tower in the town of Aleppo in modern-day Syria. Although he allowed visitors to climb a ladder to seek his counsel in the afternoons, he never left. Simeon ascended to his platform in 423 A.D. and remained until his death 37 years later.
