Social program 16 April (optional)

Join us for a beerwalk in the ancient city of Nyborg. On this 2 hour walk we will hear about - and taste - the historical significance of Nyborg in the history of Denmark; the Parliament of the Middle Ages, regicide, the Napolean wars and knight tournaments.

On our way, Peter Pelle, a local ranger and nature interpreter, will enlighten us on the unique biodiversity in the area surrounding Nyborg Castle. So come clench your thirst for history, nature and local Danish brews!
