Staff and volunteers dress in period costume, and live in the opening hours just as they would have 610 years ago. Both volunteers and employees are thoroughly trained so as to make sure that they are professionally equipped to assume the role of medieval people. 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. Volunteers are co-ordinated by the Guldborgsund Guild (Guldborgsund Gildet).
