Gundakhsaz is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Abaran district, and currently in the Aragatsotn province. The village was integrated into the former Alagoz (Aragats) district in 1972. It lies 11 km from the district centre, on the banks of the Abaran River, at a height of 2050 m above sea level. In the works of Armenian authors it is marked as “Gondaksaz”, “Gondakhsaz”, and on the five-verst map of the Caucasus as “Kondakhsaz”.

Following the Russo-Turkish war of 1877–1878, the Yazidi Kurds removed from Türkiye were settled in the village. Afterwards, the Azerbaijanis gradually left the village.

The toponym was coined by combining the Turkic word “kundak” used to mean “a weapon stock” and the Turkic word “saz” used to mean “a swamp, swampy area of groundwater, clay”.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 25 January 1978, the village was renamed “Rya Taza”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative territory of Aragatsotn province.
