The Gemjim Khatun Mausoleum is located on Cumhuriyet Street near the Ulu Mosque in Erzurum. The mausoleum, which is believed to have belonged to a woman named Firuz, dates back to the 14th century. The mausoleum was distinguished by a distinctive building style. It is a domed body with a round base in perfect harmony with the rest of the building, and the external structure is covered with arches consisting of circular tube molds. Today, the mausoleum is one of the most important tourist places for history and culture lovers.
