The Garden of Gethsemane is a 10 minute walk from the Temple Mount through the Kidron Valley and part way up the Mount of Olives.
The age of these olive trees in the Garden of Gethsemane easily date back to the days of the Crusades. A few of the trees (between 3 to 8 trees) are possibly 2,000 years old. This olive grove was stripped of trees during the war in 68-70 AD by the Romans for use as fire wood and siege equipment against the city of Jerusalem. This means it is unlikely that any of these exact trees were here at the time of Christ in 30 AD, but scholars do estimate the age of these trees to be anywhere between one and two thousand years.
