Thanks for the many responses, I am honored.
Frank, this is a castle dating back to the middle age and that was rebuilt during the Renaissance period. it is quite large and the gardens and forest cover 27 hectares, at the center of the small city of Mery sur Oise near Paris.
The place is now the property of the city, they use it as a public parc and for many local festivities, and there is also a hotel next to it (hidden in the forest) which uses the castle as a seminar house.
I live at walking distance from the castle, we often pique-nique there, or simply walk in the gardens when the weather is nice. The park is also a part of one of my jogging routines.
It is also my "long term photographic project" as I keep returning there with my IR camera, and try to find new angles on this familiar (to me) place. You must all get bored of often seeing similar-looking pictures!
