The museum presents an unusually rich collection of archaeological relics. The chronologically-presented exhibition teaches of the ancient history of the Lębork land in relation to the earliest history of Pomerania. The unique collections contain exhibitions, which were already here before the war, but the majority come from contemporary excavations conducted by the museum. The unique collection of face urns of the Pomeranian culture from the beginnings of the iron era, which show the details of human faces, and extended plant and astral ornaments, deserves special attention. The museum also has a large collection of artifacts from the period of the Roman influence. This part of the exhibition contains numerous decorations for the body, and attire made from bronze, silver and gold, metal dishes, objects for everyday use, tools and weapons. Some of the presented items were made within the territory of the Roman Empire.

This is also the home of the unique collection of medieval antiques, such as the so-called Lębork treasure – a huge collection of silver shillings from the 15^th Century – or the collection of bracteates, i.e. thin metal coins made in Central Europe from the 12^th to the 16^th Century.

Tower No. 24 hosts an exhibition associated with weapons and arms from the 14^th and 15^th Centuries. The reconstructions of the entire defence system of the city from 600 years ago are presented by a 3D-animated video.

The museum also has high-class antiques of past art – Gdańsk and Hamburg furniture from the 17^th and 18^th Centuries, which are highly valued in the cities of northern Europe. The collections of artistic craft, which include tin dishes, metal coffin fittings, porcelain and stained-glass windows, make the exhibition on the first floor of the museum a theatre of beautiful objects, confirming the tastes and customs of the former inhabitants of Pomerania.

When visiting the museum, you can also learn about the precursor of the concept of television. Lębork was the birthplace of the visionary Paul Julius Gottlieb Nipkow – the creator of the so-called electric telescope. The discovery of the so-called “Nipkow shield” led to studies on the transmission of pictures, and in turn to the creation of the world’s first- ever television set. The Paul Nipkow office arranged in the museum presents the history of television, the first television sets and other amazing technical antiques.

The exhibition on the third floor of the museum presents the residential interior of a Kashubian hut from the turn of the 20^th Century. Two rooms hold the exhibitions of material culture, which depict the appearance of the main room and the bed and drawing room. The exhibition is rich in all types of tools used by Kashubians in everyday life, from those associated with land cultivation to objects found in the Kashubian kitchen.

Tower No. 27 provides information on herbal treatment and the wealth of Kashubian models.
