About 40 km far from Yerevan there is the village of Aruch, where you can find one of the biggest churches in Armenia – St. Gregory cathedral, built in the 7th century. The cupola of the church was destroyed and now the piece of the sky, seen from the circular, opening of the cupola place, is like an uninterrupted continuation of the frescoes, once masterly painted on the walls of the church. Near the church there are the ruins of a palace, built at the same time with the church, and in the outskirts of the village there are the remainders of a castle and a caravanserai, built later in the 13-14th centuries.
