Moulay Idriss is located close to Volubilis and is considered to be the holiest city in Morocco.

The founder, Moulay Idriss, arrived here in 789 bringing with him the religion of Islam and the start of a new royal dynasty.

In addition to founding the city named after him, he also initiated construction of Fes.  This was continued by his son.

Just off the main square is the Mausoleum of Idriss I which is a sacred destination for Muslims and open only to them.

The tomb of his son is located in the Old Town of Fes.
