The island of Borgø is 17 ha. It is the largest island in Søndersø and is part of Engestofte estate. If you go to the right (west) at the jetty at Borgø and follow the path, you will see the impressive ruins at Revshaleborg.
The remains of a castle
Today there is not much left to see of the castle; only a round courtyard with steep slopes towards the water on three sides. The fourth side was protected by four ramparts with moats between them. We do not know what the buildings looked like as there are only a few bricks left.
The village of Revshale is on the mainland. Here a churchyard and traces of buildings from the 1100s have been found. A kiln, probably used when the castle was built, has also been found. The castle was probably built about 1200. Remnants of a wooden pallet bridge have been dated to 1195-1200. At this time there were many disputes and battles for sovereignty. Rebellious commoners destroyed the castle in 1256.
A popular destination
Borgø has been a popular destination for outings since the beginning of the 1800s. In the 1900s a steam boat, and later motor boats, sailed guests to the island. The tour boats sailed to the island from Maribo. Guests could also be rowed over from Revshale. The pavilion, where guests and visiting school children could buy refreshments, is now a ruin. In 1966 only a few visitors came, and the boat trips ceased. Peace and quiet settled over Borgø and the pavilion fell apart. If you look closely, you can still find remnants of the linden tree huts, and see lark, box tree, field maple and ash trees that now grow wild. Once they were part of the islands cultivated woods. Since 1993 it has again been possible to visit the island by tour boat.
The natural woods
Today almost all of Borgø consists of intact, uncultivated woods. However part of the castle area does have to be kept free of growth. Formerly the woods were dominated by elm trees. These are now almost gone due to Elm disease. In the moister areas alder and ash trees dominate.
