Pinetum de Belten is an arboretum with only conifers. This pinetum was founded by Squire Mr. P.R Feith in 1961, when he started collecting pine-trees from all over the world.

Pinetum de Belten is grown from the start to 1400 different types of pine trees. Due to lack of space for so many trees in 1992 the decision was made at around 700 trees to be grubbed up. Sub-tropical trees are removed out of the collection.Nowadayas there are more than 1000 different kinds of trees. Species must be able to grow in this environment. A single exception is made for unique items of the collection.

Since 1974 the pinetum is managed by a foundation. The main goal is to maintain and care for the collection of pine trees. Pinetum de Belten is free to visit, although a voluntary donation is very welcome.
