The Lukh Fortress is located on the site of the former Ugro-Finnish settlement of Lukh, known as the Lukh Hillfort. The latest version of the fortress was built in the 14th-15th centuries.

Initially, the fortress had an oval shape with a circumference of 277 meters, but it was later rebuilt into a rectangular form with three walls. It was surrounded by a moat on three sides, and the walls had observation slots and embrasures. A small garrison could provide its defense.

The fortress played a significant role during the Tatar-Mongol invasion and in the Time of Troubles. It was burned and rebuilt multiple times, but the last wooden fortifications were destroyed by fire in the late 18th century. To this day, only the mounds and moat remain, while the modern wooden fortification is a reconstruction.
