This stone is one of a total of six reunification stones in the former Augustenborg municipality, which were erected to mark the reunification in 1920.
After the victory of Prussia and Austria in 1864, Denmark had to cede the three duchies of Schleswig, Holstein and Lauenburg. Southern Jutland was lost, and the Danish-German border was drawn just south of Kolding. 56 years later, Germany lost World War I, and reunification became possible. After a referendum about where the border should be drawn, Southern Jutland became part of Denmark again in June 1920.
The stone was found by Andreas Blad in the water below the Palace Garden. Blad was the manager and caretaker of the Palace in the time between the reunification and the establishment of the hospital. He was very pro-Danish and made sure that the two-meter-high stone was inscribed and erected in 1925.
It was located opposite Stavensbølgade 21 (formerly Alskroen) on a piece of land called Lilleskoven. Here it was handed over to the municipality, which promised to take good care of it.
Around 1997, the municipality build a new bus stop at Lilleskoven, and since there also had to be room for a bus shelter, the reunification stone was moved to its current location at the harbour.
There was a lot of traffic at the harbour and one day the tall stone was hit by a lorry. The stone broke. The municipality chose to resurrect it, despite it now being just a little bit smaller.
