Front Gate in Kolomenskoe, Gate tower in Nagatinsky Zaton District, Russia

The Front Gate in Kolomenskoe is a tower structure at the entrance to the historical estate complex, built with stone and decorated with architectural elements typical of the period. The structure marks the boundary between the outer area and the inner grounds of the former royal residence.

Built in 1671–1673 for Tsar Alexei Mikhailovich Romanov, the gate replaced an earlier carved oak gate before the new palace. The clockmaker Pyotr Vysotsky, brought from Belarus as a war trophy, made the clock mechanism and likely helped design the whole structure. In 1767 Pyotr Makulov's reconstruction added the western street entrances.

The gate displays typical features of 17th-century Russian architecture and is now part of the protected Kolomenskoe ensemble. Visitors can see how such entrance structures once served as symbols of the owner's power and status.

The gate stands on the western side of Voznesenskaya Square, facing the Church of the Ascension. The ground-floor closets in the western pylons were cut through only in 1767, during P. V. Makulov's reconstruction; before that the west walls had windows like the east ones. A museum exhibition is housed inside the gate.

The clock mechanism was made by Petr Vysotsky, a clockmaker brought from Belarus as a war trophy in the war with Poland. Judging by the whole structure working as an organ-type noise instrument, he was likely one of the authors of the entire building, not just its clock.
