Yozgat Museum (Nizamoğlu Mansion) was included in the scope of antiquities to be protected in 1975 by the Presidency of the High Council of Real Estate Antiquities. Located in Yozgat Merkez İstanbulluoğlu Neighborhood, the mansion was built in 1871 and was used as a residence for many years, and served as a “Girls Art School” for a while and a “Tekel Warehouse” for a while. The mansion, which was expropriated in 1979, was put into service as a "Museum" in 1985 after a major repair.

Archeological artifacts are exhibited in the lower floor halls of the museum, and ethnographic artifacts are exhibited in the upper floor halls. In the upper floor rooms, rare examples of 19th century painting are noteworthy.

Nizamoğlu Mansion was originally opened as an Ethnography Museum. From 1985 to 2008, Yozgat Museum preserved its ethnographic display features, and with the latest arrangements, three halls reflecting the archaeological potential of the province were opened to visitors.
