Belton Garden Centre is built in the former formal walled gardens of Belton House. Belton House was built in the mid 1600s and the walled garden area was established in the 1800s. Unusually the 16ft walls which surround the garden centre are hollow. They were built like this to provide a cavity heating system, to supply warmth to the plants grown on the wall sides. The heating was supplied by boiler houses along the length of the wall. Plants originally grown here, mostly unseen in the United Kingdom included apricots, peaches and melons, making the owners of Belton House the envy of others for their fine fruit displays. It is reported that during the hey-day of the House over 25 gardeners were employed on the site of Belton Garden Centre.
