[1] The observatory was built between 1908 and 1910, for Admiral Vasile Urseanu, president of the Romanian Astronomical Society "Camille Flammarion".
[2] The observatory founded by Urseanu was frequented by amateur astronomers; professional researchers worked at the Bucharest Astronomical Observatory, founded by Nicolae Coculescu and located on Filaret Hill in Carol Park.
[3] Following the death of Admiral Urseanu in 1926, the telescope was dismantled and stored in the basement of the building.
In April 1950, the telescope was relocated to the dome, and the building returned to its original purpose as an astronomical observatory.
