The first Baha'i temple in Ashkabad was expropriated by the government and converted into an art gallery in 1938.

The structural design of the first Bahai temple in Ashkhabad was prepared by Ostād ʿAlī-Akbar Bannāʾ and work, which was started in 1902 and supervised by Ḥājī Mīrzā Moḥammad-Taqī, the Wakīl-al-Dawla, was completed in 1919. The temple, which served the community for two decades was expropriated by the government and converted into an art gallery in 1938. Ten years later, violent earthquakes seriously damaged the building and the heavy rains of the following years weakened the structure to the point that the Soviet authorities decided to demolish the remaining edifice and convert the site into a public park.
