The Assumption Cathedral in Gorodok was built in the ancient part of Zvenigorod, where an old fortress surrounded by ramparts once stood. These fortifications have partially survived to this day. The cathedral was commissioned by Prince Yuri Dmitrievich, who was the Grand Duke of Moscow in 1433 and 1434. The work was carried out by Moscow masters who had recently completed the construction of the Church of the Nativity of the Virgin on the Senny.

The bell tower of the cathedral was erected only in the early 19th century, and at that time, a chapel in honor of Saint George the Great Martyr was added. After the arrival of Soviet power, the church was closed in the 1930s and reopened in 1946. Since the late 1990s, it has become a dependency of the Savvino-Storozhevsky Monastery.

The history of the Assumption Cathedral in Gorodok is interesting because it is the first of the four white-stone churches of Moscow that has completely survived to this day, despite being built at the turn of the 14th-15th centuries. It stands alongside the Cathedral of the Nativity of the Virgin of the Savvino-Storozhevsky Monastery, the Cathedral of the Savior of the Spaso-Andronikov Monastery, and the Trinity Cathedral of the Trinity-Sergius Lavra.

The architecture of the Assumption Cathedral in Zvenigorod resembles Moscow buildings of that time, which are oriented towards the architecture of the Vladimir-Suzdal principality of the 13th century. However, Moscow churches have their own distinctions that set them apart from their pre-Mongol prototypes.

A feature of the Assumption Cathedral is its difference from most buildings of the pre-Mongol period. It is a small cross-domed church with four pillars and one dome. On the eastern side, there are three altar apses, while the other facades have the traditional division into vertical panels, ending with zakomaras.

The facades are decorated with pilasters with thin half-columns and carved capitals. The same half-columns separate the altar apses, the walls of which are decorated with thin vertical ties. A wide triple band of plant ornament divides the facades horizontally, smoothly transitioning into the belt of pre-Mongol buildings.

The upper part of the altar apses is adorned with a double band of stone carving, which is also present on the drum of the dome. Arches with perspective portals are located in the central panels of the facades. The originally elongated and narrow windows have only survived on the side facades and in the center of the central apse, also having framing.
