Alacali Mosque is located in the historic district of Harput, situated on high ground northeast of the center of Elazig. It is one of the notable monuments of Harput’s medieval urban fabric, near which the fortress and other religious buildings have been preserved. The mosque is usually visited during a walk through the old part of the city.

The building is generally attributed to the Artuqid period and dated to the beginning of the 13th century. For this reason, the mosque is considered one of the oldest in the vicinity of Elazig. For travelers, it is primarily of interest as a rare example of Islamic architecture in Eastern Anatolia, connected with the early stage of Harput’s development.

The name of the mosque is translated as “motley” or “variegated.” It is associated with the alternation of light and dark stone in the masonry, especially noticeable in the minaret and certain exterior details. This feature makes the building easily recognizable and helps illustrate architectural techniques characteristic of the Artuqid period.

Inside, the mosque has a rectangular plan and restrained decoration, where the main role is played by the spatial structure rather than ornament. Some of the wooden elements belong to later Ottoman-era reconstructions. Today, people come here not only for its religious significance, but also to see one of the key monuments of historic Harput.
