Construction in the Qajar prince's mansion, which became the home of the eulogists of the Ahl al-Bayt, under the name of the shrine of the unknown martyr."

The Fakhr al-Dawla Mansion is a house located on Fakhr Abad Street in District 12 of Tehran, where the daughter of Mozaffar ad-Din Shah Qajar once lived. However, as far as the neighborhood residents can remember, the tall walls around the mansion had hidden the main building from view until a few years ago, when the walls were replaced with metal railings, and the mansion's courtyard became a recreational spot for the local community.
