The acquisition, preservation, and maintenance of the places directly associated with the history of the Bahá'í faith had been among the goals of the community since its early years. These places consisted of houses and sites associated with the principal figures of the Faith, burial places of Bahá'í saints, places where the martyrdoms of believers took place, prisons, fortresses, and defense centres of heroes and renowned Bahá'ís. The fact that these places were located throughout the country made their care a major undertaking for various committees at local and national levels. The work included the registration, description, and photographing of the sites in addition to their regular maintenance and restoration. In the late 1960s more than 124 holy places belonged to the faith in various localities throughout the country. There were more than 200 national and 452 local endowments consisting of Bahá'í centres, cemeteries, hostels, and public baths.

In addition the Bahá'is had acquired 3.58 square kilometers of land on the slopes of Mount Alborz, named Ḥadīqa, in northeast Tehran, for the eventual construction of a National Mašreq al-Aḏkār. Although the temple had not yet been built a complex of buildings had been erected on the site to serve as the seat of Bahá'í summer schools and other social and administrative activities.
