After the Islamic revolution, the Zulfiqari mansion was in the possession of one of the revolutionary institutions for a long time and until the registration of this building in the list of national monuments of the country, it suffered a lot of damage due to being abandoned and not taking necessary care. During the development and widening of Taleghani Street, the wall and entrance of the building were completely destroyed. In recent years, with the implementation of urban construction projects, a lot of damage has been done to the building. Among other things, with the construction of Zainbiye Street and its passage through the courtyard of the mansion, a part of the building area was destroyed and the other major part was turned into a park.

In 1379, the cultural heritage of Zanjan province decided to protect and restore the Zulfiqari mansion, and in this regard, the said building was restored and renovated in several stages. With the transfer of the collection of artifacts obtained from the Chehar Abad salt mine in 1386, a temporary museum of mummies was established in this place, and in 1388, the first archaeological museum of Zanjan province was opened in the Zulfiqari mansion.
This building was registered in the list of national monuments of the country on 25/12/75 under number 1852.

salty men
Mard Namaki 1: Despite the exceptional discovery of Mard Namaki 1 in 1372, unfortunately, not much effort was made to shut down mechanical mining and cancel exploitation of the mine. In the fall of 2013, the miners while working with the bulldozer again encountered the remains of the human skeleton, which was largely disintegrated due to the work with the bulldozer. By searching the miners among the disturbed soils, in addition to collecting parts of fragmented human remains, a number of objects were obtained, which were transferred by the operator to the cultural heritage and tourism department of the province.

Preliminary investigations on the human remains, which were named Salt Man 2 after being transferred to cultural heritage, showed that these remains belonged to a middle-aged man with an average height of about 180 cm, who was killed during the collapse of the walls and roof of the tunnel. . Among the objects that were found with this salt man, we can mention a piece of basket and wooden nails, plant ropes, textiles, etc.
