The Hesse State Office for the Preservation of Monuments is subordinate to the Ministry of Science and Art as the highest monument protection authority and has had its headquarters in Biebrich Palace since 1967. Branch offices are located in Marburg and Darmstadt. Its work is based on the 1986 version of the Monument Protection Act (Denkmalschutzgesetz), which was passed in 1974 and stipulates that the State Office for the Preservation of Monuments has the task of advising and supporting owners and holders of cultural monuments in their care, maintenance and restoration, systematically recording and scientifically researching the cultural monuments and keeping the register of monuments. The State Office for the Preservation of Monuments is headed by a president who also acts as the World Heritage Commissioner of the Hessian State Government.

The department for the preservation of architectural and artistic monuments with a restoration workshop advises on the practical handling of monuments and is the point of contact for the lower monument protection authorities at district and local authority level with their own building inspectorate. Another specialist department is the archaeological and palaeontological preservation of monuments or "hessenARCHÄOLOGIE", to which the archaeological state museums are also assigned. It also has its own restoration workshop. An important task of the State Office for the Preservation of Historical Monuments is the recording and scientific research of Hessian architectural and artistic monuments. The State Office for the Preservation of Monuments compiles the monument topographies, which are identical to the monument book in accordance with the Hessian Monument Protection Act.

The Wiesbaden Monument Topography is available in several volumes and was published in 1988 and 2005. The results of its work are published in the biannual journal "Denkmalpflege & Kulturgeschichte" as well as in the yearbook "hessenARCHÄOLOGIE" and in publications on individual monuments. High-profile events include the annual Days of Hessian Monument Preservation and "hessenARCHÄOLOGIE" and participation in the Open Monument Day.
