A wide-angle interior view of a royal exhibition hall inside the National Military Museum at the Citadel of Salah al-Din (Al-Qala'a), Cairo. The hall features a polished hardwood floor, a large ornately carved and gilded rectangular ceiling panel with floral and geometric motifs, and a central crystal chandelier. The walls are lined with large-scale painted murals in green and gold tones, flanked by stained glass windows that cast warm yellow light across the space. The National Military Museum, housed within a former royal palace inside the Citadel, documents Egypt's military history from the Pharaonic era through modern times.
