Did You Know?
Napoleon was exiled to Saint Helena in 1815 and died there in 1821, on an island about 1,900 km from the nearest mainland. Jacob's Ladder, a staircase of 699 steps, climbs straight out of Jamestown up the valley wall.
The clock: Jamestown keeps UTC+0. The island had no airport until 2016, and the first one built proved too windy for scheduled large aircraft.
