Galacha is a village in the Borchali uezd of the former Tiflis governorate, later in the former Barana (Noyemberyan) district, and currently in the Tavush province. The provincial centre lies 54 km to the northwest of the town of Karvansara (Ijevan), at a height of 650 m above sea level.
Following the settlement of Armenians in the village, the Azerbaijani population gradually left their lands. In 1926, three Azerbaijanis lived in the village.
The toponym was coined by adding the diminutive suffix “-ça” to the word “gala” (a fortress), which implies “a village near a small fortress”. The ruins of the 12th-13th-century fortress related to the life of Azerbaijanis still remain in the southeast of the village. The village derived its name from that fortress.
By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 25 January 1978, the village was renamed “Berdavan”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Tavush province.
