Tapanli is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Hamamli (Spitak) district, and currently in the Lori province. The center of the province is located 26 km to the northwest of the town of Boyuk Garakilsa (Vanadzor), on the right tributary of the Beykand River. It was marked on the five-verst map of the Caucasus.

The village was originally inhabited by Azerbaijanis, but following the settlement of Armenians from Türkiye according to the Treaty of Adrianople (1829), the population gradually left the town.

The toponym was coined on the basis of the Turkic ethnonym “Tabanli” (Tapanli), the descents of the Aghgoyunlus who lived in Diyarbakir.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 25 January 1978, it was renamed “Geghasar”. 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 Lori province.
