The Lublin Underground Trail runs under the Market Square and the tenement houses of the Old Town, the length of which is approximately 280m. The route was created as a result of joining a dozen of numerous old town cellars, the history of which dates back to the beginning of the 16th century, i.e. the century of Lublin's greatest glory.

The route is of a tourist and educational nature. A walk through the historic old town cellars, which in itself provides many emotions, is also a journey in time that allows you to discover the past of the city. The history of Lublin's spatial development is presented in an exhibition consisting of a series of models showing the settlement in the area of ​​the present city, from the early Middle Ages (8th-10th century) to the 18th century.
The climax of the underground story is, enriched with light and sound, a moving model of the Great Lublin Fire (1719). The visualization, referring to the tradition of mechanical theaters, was created on the basis of a painting that is a memento of those events and located in the church of the Dominican Fathers.

Lublin Underground Route connects two places important for Lublin: it starts in the former town hall, i.e. in the center of secular authorities, and ends on the square where the church of St. Michael, focusing for centuries the religious life of the city. Two most important legends of Lublin are also connected with these points: the town hall (Crown Tribunal) The legend of the devil's court (the so-called The legend of the devil's paw), and the parish church The legend of Leszek the Black's dream.

We will meet the characters from the first of them (Lublin devils), enchanted in wood, in the basements of the Tribunal and underground corridors, and we can play the characters of the last one by taking a commemorative photo in the "monidle" at the exit of the Route.

The exhibition, referring to the history of Old Town buildings, is complemented by fragments of historic architectural decorations of tenement houses, forming a small lapidarium, as well as barrels and other containers made of wood referring to the former storage functions of the premises of today's Route.
