The House Martin (Delichon urbicum) has been a resident of Lütetsburg for several generations and nests mostly in the inner courtyard of the castle as well as in the outer castle in the old stables - thus it is not only a defining feature of the image and atmosphere of Lütetsburg Castle, but has also found a habitat in which it can live and nest without being endangered by humans.
The House Martin uses the rough walls and eaves of the buildings to build its elaborate clay nests. They prefer to nest near water, as they are particularly good at catching mosquitoes, flies and other insects in flight.
House martins are recognisable by their blue-black head, back, upper wing and tail and the contrasting white of the rest of their body. They grow to about 13 cm, therefore smaller than a sparrow.

Here are some ways to get actively involved in our climate projects - we would be happy if we could inspire you to support us and become active yourself.
Schloss Lütetsburg maintains several so-called field copses. These are mostly small groups of woods under one hectare in size, which are intended to serve as shelter for game and other animals.
Lütetsburg Castle owns the Lütetsburg Forest, the Knyphauser Forest near Wittmund with almost 750 hectares, as well as another 300 hectares of forest spread over several federal states - enough area, in other words, to play an important role in the climate as well as water balance and quality.
Already, areas of about 15 ha (150,000 sq m) have been converted into bee meadows on a voluntary basis to create new habitats for the endangered species and other insects.
