On the picturesque bank of Akhuryan river there is the magnificent monastery Marmashen built by Duke Vahram Pahlavuni. It is a huge complex, the construction of which started in 986 and finished in 1029. The main church is a domed hall. The facades of the church are elaborated with triangular niches, which endow the edifice with special liveliness.
