A great town of Devkesken, Devkisken or Deu-Kesken kala
is situated about 60-70 km from Kounya-Urgench in the
north-west and is the remains of a lively medieval town
Vazir that stood once above the channels of Amudarya.
The ruins of the town are situated on the steep and high
stone plateau surrounded by the deep moat and walls.
At the corner of the plateau the remains of a great castle
has been found where one could trace the relief of the
beautiful cylindrical facades that were typical to the
architecture for the early medieval pre-Arabic period.
Town of Vazir must have lost its significance in XVI century.
On the territory of town there is a number of mausoleums
of burned bricks and stone that dates back to the XV century.
In the middle of XVI century Vazir was the residence of
one of the Khoresmian khans named Sultan Ali. However
successor of sultan had moved the khans residence
to Urgench. It had happened in 1573 when bifurcation of
waters of Amudarya had been observed and the river had
directed a channel to Aral Sea. The ruins of the separate
constructions have been discovered as well and among them
one can see oviparous cupola of architectural ensemble
of Seid-medrese typical to XIX c.
