On Tuesday, the excavation of a huge facility on Falster, which is supposed to be the country's largest Viking castle, starts.
When the archaeologists on Tuesday put the shovel in the ground on Falster, it may be that finds appear from the ground that may change the known Danish history in the Viking Age and in the Middle Ages.
Here begins the archaeological investigations of a huge Viking castle, which in recent years has been investigated discreetly on Falster. Archaeologists believe that the Viking castle is the largest of the castles known so far in Denmark.
This is not a ring castle - but a much larger facility in size, which apparently for centuries has played an important role in Falster's defense and organization.
So far, it is listed as Denmark's largest castle from the Viking Age, and a conservative estimate from the researchers behind the find is that it has been in use from 850 until 1250. However, the castle has apparently been used before then.
With more than 10 meters high ramparts, it has risen impressively on top of a large hill in the middle of Falster, and has been a demonstration of power in its time. That's what Leif Plith Lauritsen from Museum Lolland-Falster says.
It is a place where the legendary kings met. The embankment can play a crucial role in relation to how we are to understand the history of Falster and Lolland - and the whole story of how Denmark came to be. The construction of the castle has been a huge project in terms of size, says Leif Plith Lauritsen to TV2 EAST
The castle is located near Virket Lake by the small town Virket on Falster, and Leif Plith Lauritsen is together with archaeologists and students from Aarhus University behind the excavation, which starts next week. The excavation is carried out with support from Queen Margrethe II's Archaeological Foundation.
Lars Sass Jensen from Aarhus University calls the castle impressive.
According to the medieval expert and the now retired museum director Niels-Knud Liebgott, the castle is a completely unique find in Denmark - and also in the world. He has worked with medieval archeology in Denmark for many years.
He does not participate in the excavations, but has been to the castle and heard about the finds that precede the excavation that starts on Tuesday.
He believes that the size suggests that the plant may be much older than the previous dates suggest.
The well-known historian Saxo has described the mighty battle, in which an army from the Land of the Venders in present-day Germany and Poland was repulsed by a fortification called the Joint Forces' Joint Forces.
For almost 100 years, it has been assumed that there was a system of violence in a system of violence in Hannenov Forest, where a memorial stone for the battle has also been erected.
Now, however, the researchers have abandoned that theory, and believe instead that the newly found castle by Virket Sø was Falster's Virke.
The assumption is based, among other things, on carbon-14 dating of fire layers found in the castle's ramparts.
However, the dates also surprised the researchers. It was the first time that they found out how old a plant was. At the same time, the division into layers of the violence showed that the castle has been in battle many times over time.
The many and thick fire layers on the castle also move the castle's history away from the Middle Ages and far back in time. The oldest dated layer is dated to the time around the year 900, probably 880. However, six layers have been excavated under this fire layer - and according to archaeologists, they expect to find even more layers below this.
At the same time, they have been able to document how the defenses after each battle have been rebuilt, and generation after generation have been built bigger and stronger.
One of the goals of the excavation in the coming week is to find out how old the facility actually is.
Leif Plith Lauritsen was convinced that it was a refuge castle, until on the last day of the first test excavation they found a paved road along the ramparts. It was a very important find because the road was laid in one of the early stages of the castle's long career.
This suggests that the castle has been far better fortified and organized than first assumed.
However, the castle may also have been a local place of worship, a trading place that has been fortified - or may have been the site of the discovery of one of Denmark's oldest cities - perhaps 'Gammelkøbing', whose role was later taken over by Nykøbing, which is almost 10 kilometers gone.
A city within the ramparts may, however, be the explanation for the fact that it is such a large castle. Such castle-like facilities abroad are often seen around cities - although they do not quite resemble this facility, says the independent expert Niels-Knud Liebgott.
However, he does not expect the answer to come within a manageable time horizon.
According to experts, the location of the castle is anything but random.
Furthermore, the castle is located only an hour's walk from the large Viking shipyard Fribrødre Å near Stubbekøbing, where both Danish and Wendish ships have been maintained over time. The shipyard is the largest known shipyard in Denmark in the Viking Age, and was more than a kilometer long.
- The discovery of the castle is part of a story in which there were some important institutions and facilities during the Viking Age. We know that the two plants were simultaneous, and of course they have known each other. However, we can not say whether they have been on the same team throughout history. But if they have known each other, then they have been able to seek refuge here, says Leif Plith Lauritsen.
He believes that the coincidence, in addition to a number of references in Saxo, among others, helps to emphasize the story of great Viking activity on northern Falster.
The yard is well protected from sudden raids inland. And it is clear that either Trygge Castle or a rampart not yet found inland could have been their rampart. But where the shipyard at Fribrødre Å has probably been wholly or partly controlled by the turners for periods, it is not certain that the same applies to the castle, he says.
He calls the shipyard a strange shipyard because Slavic ships with clear Danish features were built and maintained, and he wonders whether changes in culture may reflect that the local prince or king in periods such as in a special Baltic Sea edition of the Games of Thrones might have changed sides if that made sense to him.
There is no doubt that the area here has played an important role in the struggle to win power in Denmark. But whether we have been on the winning or losing side at the end of the Viking Age, we can not say yet.
The excavation starts according to plan immediately after Pentecost, and is scheduled to last for two to three weeks.
Here, several different places in the facility must be dug. Partly in some of the areas that have already been studied - but also completely new places. The aim is to determine the age and significance of the plant.
We dig both in the southern ramparts, which we have already investigated - but also in the central ramparts and the northern ramparts. And besides, we do some search fields along the way. Our hope is that in this way we can gain new knowledge about the plant's long history, says Leif Plith Lauritsen.
