@Tetters the shortened version.
The house and gardens were first laid out in 1906. For years, the place made a noce profit. Then, starting somewhere around the mid 1980's, it fell into economic difficulties, fell into disrepair, and was declared bankrupt. As I understand things, the purchasers planned to demolish it, and build high end, therefore expensive housing.
There were a lot of protests which seemed to come to nothing. Then, it was discovered that an endagered lizard (
Lacerta agilis?) crossed the area to its breeding ground. If the houses were built, that would not be possible. Making the species even more endangered. Conservationists, as well as others got involved, things went to court, found in favour of the lizard, and therefore the building plans had to be cancelled!
So, the house and gardens were restored. The last tume I went there was in 2016. By that time the place looked great, and back to its former glory. I enjoyed all aspects of the place, especially the huge knot garden.
If I can dig out some photos, I may just start a topic on it. No promises though!
