Jerusalem Gates in Wikipedia
During the era of the crusader Kingdom of Jerusalem, there
were four gates to the Old City, one on each side. The current
walls, built by Suleiman the Magnificent, have a total of
eleven gates, but only seven are open. Until 1887, each gate
was closed before sunset and opened at sunrise. As indicated
by the chart below, these gates have been known by a variety
of names used in different historic periods and by different
community groups.
