Stopping short of actual time travel the Wallace Collection will do its best to convince that you've stepped back a few hundred years with a "Day in the 18th Century" on Saturday 26 February.
Imagine 1759 and visit the world of Madame de Pompadour to celebrate 18th-century French arts.Play cards with elegantly dressed nobility, listen to costumed interpreters, period music will transport you, gallery talks and lectures will inform and entertain you.
Keep the kids busy with things to make and - if you dare - let them learn to sing, opera style. Grown ups can get to grips with some princely pistols, be educated about architecture and ruminate on Voltaire's writings. Just don't get carried away and forget to discover the Wallace Collection of French paintings, porcelain, furniture and gold boxes from the period, which they claim is probably the best to be found anywhere outside France.
As always, access to the Wallace Collection is free to all but there is a £2 suggested donation. Open 11am-4pm at Hertford House, Manchester Square, London W1U 3BN.
