The Case

The Case acts as a protective cover for the tender plants grown here. Originally called the Conservative Wall and designed by Joseph Paxton in 1838, it is backed by an ingenious system of flues and hot-water pipes, to keep the temperature high enough in the winter for half-hardy plants to grow successfully. Initially, there were projecting wooden panels from which canvas curtains could be hung in the coldest weather, but in 1848 Paxton covered it with a wood and glass frame.

The structure is 91m long, and protects figs, peaches, nectarines, apricots and various shrubs from the unpredictable Derbyshire climate.
