The Sultaniyya Mausoleum, located in Cairo's Southern Cemetery, is a notable example of 14th-century Mamluk architecture. Constructed in the 1350s, it is believed to have been commissioned by Sultan Hasan in honor of his mother, though her exact identity remains uncertain. The mausoleum is distinguished by its two ribbed stone domes with pointed profiles, resting on high drums adorned with intricate Kufic inscriptions. Between the domed chambers lies a large iwan, featuring a stone mihrab embellished with muqarnas carvings. Originally part of a larger complex that included a khanqah, the structure has faced challenges due to urban development, including the disassembly of its minaret in 2023 to accommodate new infrastructure projects.
