The Salihiyya Madrasa (or Madrasa as-Salihiyya), also called the Madrasa and Mausoleum of as-Salih Najm ad-Din Ayyub (Arabic: مدرسة وقبة الصالح نجم الدين أيوب, romanized: Madrasa wa Qubbat as-Salih Nagm ad-Din Ayyub) is a historic madrasa and mausoleum complex in Cairo, Egypt. The complex was founded by the Ayyub sultan As-Salih Ayyub in 1242 and his mausoleum was added to it by Shajarr ad-Durr upon his death in 1249. It was one of the most prominent centers of Islamic learning in the Ayyubid and Mamluk era in the 13th–14th centuries CE. Its remains are located on al-Muizz Street in the historic district of Cairo across from the Complex of Sultan Qalawun.[1]
