Qasr al-Basha — the Pasha's Palace, also known as Radwan Castle or Napoleon's Fort — was a Mamluk-era fortified residence in the Old City of Gaza, built in the thirteenth century by Sultan Baibars. The two-storey limestone building was a rare survival of pre-Ottoman domestic architecture in Gaza, with thick walls, vaulted ground-floor chambers, and a small interior courtyard.
For most of the twentieth and early twenty-first centuries it housed the Pasha's Palace Museum, with archaeological material gathered from sites across the Gaza Strip — pottery, mosaic fragments, glass, and inscriptions ranging from Bronze Age to Ottoman. The building was destroyed by Israeli airstrikes in December 2023; most of the museum collection was reportedly lost.
