Sidi Yahya Mosque (Timbuktu)

Sidi Yahya Mosque is a historic mud-brick mosque and madrasa in the city of Timbuktu, traditionally dated to construction begun around 1400 and finished circa 1440. It is named after its first imam, Sidi Yahya Tadlesi, and is one of the three great mosques associated with Timbuktu's medieval scholarly community. The mosque complex includes associated saintly tombs and burial grounds that have been important in local Sufi and devotional practice. A widely reported local/Sufi legend holds that a particular door of the ancient Sidi Yahya Mosque must remain sealed and not be opened until an appointed time; opening the door is locally said to precipitate apocalyptic consequences. This belief was recorded in international legal proceedings concerning events during the 2012 Islamist occupation of Timbuktu, which noted the statement: "We heard about a door in the ancient mosque of Sidi Yahya. If it is opened, the Day of Resurrection will begin." News and heritage reports from 2012 describe Islamist fighters attacking or setting upon one of the mosque's doors in actions framed as challenging that legend. During the 2012 occupation several medieval saintly tombs in Timbuktu were reported destroyed by Islamist extremists; contemporaneous reporting and heritage commentary emphasize that these attacks targeted tombs and doors as symbolic assaults on local Sufi traditions. The provided sources focus on the cultural and eschatological significance of the sealed-door legend and on the documented attacks; they do not record firsthand supernatural sightings such as apparitions or poltergeist phenomena. The precise present-day physical condition of the specific door and of all tombs referenced in the 2012 reports is not detailed in the provided material.
