Gorodok, Archaeological fortress in Zvenigorod, Russia.

Gorodok is a medieval hillfort and archaeological site in Zvenigorod, Russia, set on a steep promontory above the Moskva River. The earthen ramparts still encircle the entire area, and a 14th-century stone cathedral stands within the walls.

The site was used as a fortified settlement from the 12th and 13th centuries and later became the center of the Zvenigorod principality. In the 14th century, Prince Yuri Dmitriyevich had a stone cathedral built here, marking the height of the settlement's importance.

The Assumption Cathedral inside the site contains frescoes from the late 14th century, attributed to painters of the early Moscow school. These murals are among the earliest known examples of this tradition and can be seen by visitors today.

Paths through the site can be steep on the slopes, so sturdy footwear is a good idea before heading up. The site is generally open to visitors throughout the year, though dry weather makes the terrain much easier to walk.

Although the fortress was abandoned over the centuries, the earthen ramparts survived almost unchanged, which is rare among medieval fortifications in this region. This made the site a reference point for archaeologists studying how medieval Russian defenses were built.
