Rozhen Observatory (Bulgarian: Национална астрономическа обсерватория "Рожен", НАО-Рожен - NAO-Rozhen) is a Bulgarian astronomical observatory, located 90 km south of the city of Plovdiv, Bulgaria. The nearest town, Chepelare, is 15 km away. The observatory is owned and operated by the Institute of Astronomy of the Bulgarian Academy of Sciences. It was officially opened on 13 March 1981, almost 20 years after Bogomil Zhivkov Kovachev (a Professor of Astronomy at BAS, known as its founder) had started working towards that goal.[1][2] The Observatory is the largest in Southeastern Europe[3] and has an active team of about 50 astronomers. It is the principal center for astronomical research in Bulgaria.[citation needed]
