When visitors to Jerusalem are shown a large cave called "Gethsemane" on the lower slopes of the Mount of Olives, they usually give a perfunctory look and hurry on to the famous Garden of Gethsemane, the small garden of olive trees adjacent to the Church of All Nations. Here pilgrims can sit and reflect on the momentous events of Jesus' arrest in what seems a more appropriate, if less authentic, environment.

Most of these pilgrims are never told that the New Testament does not mention a "Garden of Gethsemane." The Cave of Gethsemane, on the other hand, is very probably a genuine Biblical site-the location of Jesus' arrest-unlike so many of the "traditional" holy sites of Christianity that have little or no claim to authenticity.

The cave, within a property now owned by the Franciscan Custody of the Holy Land, certainly looks unimpressive. Enclosed in a flat-roofed, semicircular building, the cave is reached by a long corridor to the right of the courtyard leading to the traditional Tomb of the Virgin. Its placement makes it seem an afterthought, though in fact it was a Christian holy site long before anyone thought to place the Tomb of the Virgin Mary beside it. The interior of the rather spartan cave has traces of two levels of Byzantine (fourth-sixth-century) mosaics, intriguing medieval ceiling and wall decorations, and modern altars on a modern stone floor. These features, however, do not seem too inspiring to most visitors
