The Bab al-Yemen ("Yemen Gate") is the great southern entry to the walled old city — a stone-built arch with arrow-loops and a small mosque set above it, opening onto the main square of the medieval quarter. The current structure dates from the Ottoman period, but a gate has stood here for at least a thousand years and probably much longer.
The square just inside the gate is the busiest space in the old city: a tangle of stalls, money-changers, and porters, and the natural starting point for any first walk into the souks. Outside the gate, the broad open area called Maydan al-Tahrir hosts qat-chewing crowds in the afternoons.
