The Yamishevsky Gate is one of the earliest architectural buildings in the city of Semey that has survived to this day. The building is an architectural monument of the 18th century consisting of a tall arched roof and a vaulted arched building. The wall thickness of the arch is 2 meters and the depth is about 10 meters. The top of the wall is rounded to form a small tunnel. Yamyshevsky Gate is maximum height of 7.43 meters, length of 7.27 meters, the width of 7.79 meters. At present, the Yamishev fortress gate is completely rebuilt and strengthened by the lock and the ring. The gates have an unusual history and a difficult fate. The Yamishevsky Gates is the only surviving part of the once formidable Semipalatnaya Fortress, erected hereby the order of Peter I in 1718. Originally, the fortress was laid elsewhere, but the constant spring floods of the Ertis River forced the fortress to change thrice. And only in 1718 engineers and builders could find the safest place for building a fortress. The fortress was located on the right high bank of the river and was surrounded by a high wooden wall with earthen ramparts and moats. For all the time of its existence the structure has been repeatedly rebuilt and strengthened. In 1773 the fortress walls and gates were erected according to the design of the engineer - captain I. Andreev. The constructed Semipalatnaya fortress had three gates: Semey, Yamishevskie and Oskemen. Of all the gates to this day only the Yamishevskys have survived, but they have suffered a difficult fate. At the beginning of the first half of the XX century, the fortress lost its military significance, but some of its parts, including the western Yamishevskie gates, were decided to be preserved as architectural monuments. However, with the onset of Soviet power, everything changed and in 1932 the question arose about the destruction of the Yamyshevsky Gates. Fortunately, the gate managed to be preserved. But soon, in 1941, the City Council again raised the question of the demolition of the architectural monument. In May 1941 it was decided to repair and restore the gate. In this difficult time it is still managed to defend the architectural monument, but, unfortunately, not for long. Already in 1970, the Yamyshevsky Gates became an obstacle in the construction of a tunnel for access to the railway. Therefore, the local authorities decided to move them to 40-50 m closer to the Ertis River. The gate was first disassembled, and then built in a new place. Builders have preserved their external appearance, but this is not that original historical monument.
