Built in 1872, this house used to belong to one of the wealthiest people in Gyumri, Petros Dzitoghtsian, living in the Alexandrapol period. Original luxurious interiors of the rich house owner are on display in the house-museum. The building is built with the famous red tuff stone of the Shirak region.
