Axum Tsion St. Mary, or the Church of Our Lady Mary of Zion, located in Aksum, Ethiopia, is a profoundly significant religious site believed to house the Ark of the Covenant. The complex is generally accessible by foot within Aksum, though some parts, like the Old Cathedral, involve steps and uneven paths; mobility within the site requires walking, and women are not permitted inside the Old Cathedral. A local guide is highly recommended to fully appreciate the historical and religious context of the churches, museum, and treasury, making solo visits less informative. The dry season (October to May) is ideal for visiting, avoiding the rainy season's potential travel disruptions, although major religious festivals like Timkat (January) offer unique, albeit crowded, experiences. Expect an approximate cost for the Aksum archaeological park entrance fee (which covers this site) plus separate guide fees. A typical visit duration is around 2-3 hours, allowing time to explore the Old and New Cathedrals, the museum, and view the exterior of the Chapel of the Tablet. Visitors must dress modestly (shoulders and knees covered), remove shoes before entering churches, and note strict photography restrictions inside some buildings; access to the Chapel of the Tablet is highly restricted.
