Belgium hosts the highest density of castles in the whole world.

The Gravenkasteel in Humbeek
With approximately 3000 castles, farm-castles, citadels, manors or palaces, there is plenty of beautiful architecture to admire.
In the densily populated lowland areas of Western Europe, castles – and especially castle parks – are a blessing for biodiversity. It is there that some of the rarest but most precious habitat types are still flourishing.
This kind of Belgium nature is a much smaller-scale beauty than the endless uninterrupted Swedish mountains, but I promise you the Belgian castles stand their ground in any global beauty contest.
