Everyone rushes uphill to the Citadel's Muhammad Ali Mosque, completely missing Al-Rifai's magnificent facade below. This late 19th-century architectural masterpiece was deliberately designed to match medieval Mamluk style so perfectly that most visitors assume it's genuinely medieval. It houses Egypt's royal family tombs, including the last King Farouk.

Architectural highlights: The interior dazzles with massive marble columns, intricate geometric patterns, and polychromatic marble work that rivals any European cathedral. The royal burial chamber features ornate sarcophagi in a setting that feels appropriately majestic for Egypt's final monarchs.

Practical information: Open daily 9 AM-4 PM, free entry with conservative dress required. Women need head covering (security provides scarves if necessary). Located at Citadel entrance - combine with fortress visit for historical continuity. Guards often offer informal tours of royal tombs if you show genuine interest and speak some Arabic courtesy phrases.

Photography tip: Visit late afternoon when western light illuminates both Al-Rifai and the Citadel above, creating stunning architectural contrast shots. From the Citadel's plaza, you can capture both structures together - medieval fortress crowning modern royal mosque in one frame. This perspective reveals Cairo's layered Islamic architectural heritage beautifully.
