Viewed through a pointed Gothic-style stone arch, a group of tourists walks and photographs along the stone sea wall promenade of Qaitbay Citadel in Alexandria, Egypt, with the turquoise Mediterranean Sea visible in the background. Qaitbay Citadel (القلعة قايتباي) is a 15th-century Mamluk fortress built in 1477 AD by Sultan Al-Ashraf Qaitbay on the eastern tip of Pharos Island, where the ancient Lighthouse of Alexandria once stood. The framing through the arch emphasizes the fortress's medieval military architecture and its direct relationship with the sea.
