The buildings on the left are stables. The buildings on the right house a couple of restaurants. They're all part of the park.
Most of the park is forested and for centuries was used as royal hunting grounds. In fact, I understand that royal hunting parties ventured well beyond the confines of the castle walls.
We had thunderstorms overnight, but they were relatively mild and didn't last long. I was up at 03h20 and out on the deck. The clouds were parting and I saw a bright light moving through the northern sky. I made a mental note of the time and then looked at the internet this morning to verify that I indeed saw the International Space Station pass by. Cool.
