Garden of Gethsemane is an urban garden at the foot of the Mount of Olives in Jerusalem, most famous as the place where Jesus prayed and his disciples slept the night before His crucifixion and is the site recorded as where the agony in the garden took place.
According to the Eastern Orthodox Church tradition, Gethsemane is the garden where the Virgin Mary was buried and was assumed into heaven after her dormition on Mount Zion. The Garden of Gethsemane became a focal site for early Christian pilgrims. It was visited in 333 by the anonymous "Pilgrim of Bordeaux", whose Itinerarium Burdigalense is the earliest description left by a Christian traveler in the Holy Land. In his Onomasticon, Eusebius of Caesarea notes the site of Gethsemane located "at the foot of the Mount of Olives", and he adds that "the faithful were accustomed to go there to pray". Eight ancient olive trees growing in the Latin site of the garden may be 900 years old.
In 1681 Croatian knights of the Holy Order of Jerusalem, Paul, Antun and James bought the Gethsemane Garden and donated it to the Franciscan community.
A study conducted by the National Research Council of Italy in 2012 found that several olive trees in the garden are amongst the oldest known to science. Dates of 1092, 1166 and 1198 AD were obtained by carbon dating from older parts of the trunks of three trees. DNA tests show that the trees were originally planted from the same parent plant.
