1. The Garden of Gethsemane is a biblical site located on the Mount of Olives in Jerusalem, Israel. It is believed to be the site where Jesus prayed on the night before he was crucified, and is therefore an important pilgrimage site for Christians. The name \"Gethsemane\" comes from the Aramaic word for \"olive press\", as this area was known for its olive groves and presses. The garden has eight ancient olive trees, some estimated to be over 2,000 years old, and a number of other religious monuments and structures.

2. The Garden of Gethsemane is open to visitors from 8:30am to 6pm daily, except on religious holidays. The garden does not have an official phone number, but is located next to the Church of All Nations which has a visitor’s center.

3. Admission to the Garden of Gethsemane is free. It is accessible by car or public transportation, such as bus or taxi. Visitors can also reach the site by walking or biking from other parts of Jerusalem, such as the Old City or Mount Scopus.
