The Khalid ibn al-Walid Mosque is a historic mosque that developed around the mausoleum attributed to the Companion Khalid ibn al-Walid. Although it is said that a place of worship existed around the mausoleum as early as the early Islamic period, the major structural phase reliably documented is the mosque built in 1265 during the reign of Mamluk Sultan Baybars I; the structure was restored in 1291 during the reign of Sultan al-Ashraf Khalil. The old Mamluk mosque was documented in its pre-demolition state in a series of photographs of Homs, likely taken during Max von Oppenheim’s 1899 journey through Syria. The current mosque, however, was rebuilt in place of the old Mamluk structure during the reign of Abdulhamid II in the late 19th–early 20th century, with construction completed in 1912. Thus, while the building primarily belongs to the late Ottoman architectural style, it preserves the tomb of Khalid ibn al-Walid and continues an even older religious tradition. The mosque sustained heavy damage during the 2011–2013 conflicts but was later restored and reopened for use.
