The employees are dressed in period costumes and live and work in the houses and do everyday activities such as craftmanship, cooking and weapon training.

In addition, a support association exists, from which a large group of volunteers participates in the daily work.

The Middle Ages Centre started with the reconstruction of a medieval siege weapon, called a trebuchet, built to mark the 700th anniversary of Nykøbing Falster in 1989.

Given the considerable interest in the trebuchet, a scoping project, "Medieval Technology Centre", was conducted for two months in the summer of 1991.

Living history is central to The Middle Ages Centre and the focus is a Danish market town in the period around the year 1400.

The purpose of the work is partly dissemination, but also academic research, especially in the form of so-called experimental archaeology where ancient tools and technology is reconstructed on the basis of extant sources and objects in exhibitions around the world, and then tested in practice.

[21][22] Neither glasses nor piercings are allowed and the inhabitants don't know about mobile phones, TV or other modern things, as these are not a part of the concept.

[24] The museum has a restaurant called The Golden Swann, which is furnished as a dining hall at a major Danish castle around 1400.

[11] The centre participated in the third Galathea expedition (2006–2007) and researched both sulfur and saltpeter in black powder production in Puducherry, India and transportation to Europe.

During these specific festivals, the time period and region of interest being portrayed been extended to embrace broader medieval life.

A historical reenactment society from King Edward's School, Birmingham have visited the museum several times as a part of their education.

Thus both National Geographic Channel has recorded a documentary about early inventions such as diving equipment and throwing machines[35] and the Danish movie Vølvens Forbandelse and the German film 12 Paces Without a Head has scenes shot at the centre.
