Zawiya of Moulay Idris II is a historical Islamic Zawiya (A religious complex includes mosque and madrasa). It is located in Fes el Bali, Fes, Morocco. The complex includes the tomb of Idris II (791-828), who was the son of Idris I, the founder of the Idrisid dynasty in Morocco. The date of the oldest zawiya is uncertain, as it is believed to date back to the period between 9th to 13th centuries AD, while the current zawiya dates back to the Marinid period in the 14th century AD. The zawiya was later restored and expanded during the Saadi and Alaouite periods. The Zawiya of Moulay Idris II was inscribed as a UNESCO World Heritage Site in 1981 as part of Medina of Fez.
