This building, like many on the estate, was locked up, seemingly abandoned. But, as a hothouse, still containing a whole host of vigorously blooming plants in the deep mid-winter. You can walk all the way around peering in through moss covered panes at the flowers which were all the more beautiful for being unattainable. It was like peering through the mottled eye-glass of a time-telescope (aren't they all?) into a world that can be only dimly perceived.
