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. The survived eastern and northern walls of the second church, which is adjacent to the main church, prove that both with its composition and architectural details it is the smaller duplication of the main church. This complex, built with well-hewn red tufa on the background of the blue sky, casts an enigmatic impression.
