Deene Park, Northants

Private
A substantial house, with crenellations, and built of honey-coloured stone around a central courtyard. The earlier parts date from the 16th centurey or earlier, with 18th and 19th century additions. The contents include relics of Lord Cardigan of Balaclava fame, and of the scandalous Adeline Horsey de Horsey. The house is open on limited dates during the summer months.
The contents are of considerable interest and rooms downstairs and upstairs are opened for visitors.
The grounds are worth seeing and include a number of feature garden areas as well as woodland walks and an expanse of lawn. Not accessible to visitors are the former walled gardens and an intriguing circular building.
If you want a leisurely visit to the house, the grounds, and the tea-room you are advised to arrive soon after the grounds open as the total opening time is only 4 hours.
If using satnav, look for brown car park signs, as the satnav may direct you to a back entrance by a longer route.
Note that there are other grand houses in the Corby area which could be visited on the same day. Kirby Hall is nearby.
