Vallø traces its history back to the 14th century. From 1554 to 1651 it was divided into two separate estates, West Vallø and East Vallø. In 1708 Vallø was acquired by King Frederick IV who passed it on to Anne Sophie Reventlow. In 1731 King Christian VI passed the property on to Queen Sophia Magdalene who in 1737 founded the Noble Vallø Foundation for unmarried daughters.
Vallø consists of four wings with robust towers and is surrounded by a moat. The south wing, with its robust corner towers, and the south end of the west wing were built from 1580 to 1586 by Mette Rosenkrantz, one of the richest women in Denmark of her day. In Christen Skeel's time of ownership, from 1638 to 1659, the castle was expanded to three storeys and the west wing extended. The north wing was built by Johan Cornelius Krieger in 1721. A three-winged building designed by Lauritz de Thurah was built in the courtyard from 1735 to 1738. The surviving central wing expanded with an extra storey by Georg David Anthon in 1765. The castle was devastated by fire in 1893 but restored largely to its old design by Hans Jørgen Holm between 1893 and 1904.
The park was turned into a Romantic landscape garden in 1830 but retains elements from the former French gardens from the 1720s. I large flower park was founded in 1960 but it has later been disbanded. Next to castle and its park there is a cluster of historic houses arranged around a street known as Vallø Castle Street (Vallø Slotsgade). Vallø Castle Inn received a royal privilege in 1784. The estate also owns a variety of other houses spread out across the surrounding countryside.
The estate is still owned by the Vallø Foundation (da. Vallø Stift) and covers 4,109 hectares of land of which 1,860 hectares are woodlands. Apart from agriculture and forestry, the revenues derive from house rental, the inn, a campground located close to Køge, and hiring-out of hunting areas. The castle still provides housing for women of the Danish nobility but since 1976 admission to the residences is not restricted to unmarried women but now also cover widows and divorced women.References:
The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
