91 years ago, on June 20, 1934, the first planetarium in Bulgaria was opened in the building of the National Astronomical Observatory in Sofia. The facility, equipped with a German optical-mechanical system, allows for a realistic reproduction of the starry sky on a dome and gives hundreds of students, students and citizens the opportunity to get acquainted with astronomical phenomena.
