Two postcards of Den Alerdinck show bridges (or just one of them from different angles) that once adorned the garden. The postcards are roughly dated 1949-1969, whether the photo’s were taken in this period is uncertain. The bridge(s) are probably built in the late 19th century, but that is a (my) wild guess. In stead, there is now a bland bridge that merely serves to get you to the other side -minimalist and dull.
The location where this bridge (or bridges) was, is currently private property and can only be used by the owners and their guests. If the chance of vandalism is this small, why not recreate these bridges in the spirit of the previous owners of the estate?
