• Emma Hamilton, the mistress of Horatio Nelson – hero of the Battle of Trafalgar, is the subject of a new exhibition at the National Maritime Museum in Greenwich. One of the most famous figures of her time, Hamilton rose from obscure beginnings to the heights of celebrity and is best remembered for the scandalous affair she had with Lord Nelson for the six years prior to his death in 1805. Emma Hamilton: Seduction and Celebrity brings together more than 200 objects, many of which have never been displayed before, including paintings, letters, costumes and jewellery. Highlights include works by artists George Romney, Sir Joshua Reynolds and Sir Thomas Lawrence, letters from Hamilton and her lovers, betrothal rings exchanged between Hamilton and Nelson, her songbooks and decorative objects. The exhibition, which runs until 17th April, is accompanied by a series of events including walking tours and late openings. Admission charges apply.

• Sir Joseph Lyons, founder of Lyons tea shops and the ‘Corner Houses’ of London – among the first chain restaurants in England, has been honoured with an English Heritage Blue Plaque at his former home in Hammersmith. Sir Joseph, who lived at the property in the 1890s close to the now-demolished headquarters of his catering empire at Cadby Hall, opened the doors to his first teashop at 213 Piccadilly in 1894. He was knighted by King George V in 1911. For more, see www.english-heritage.org.uk/visit/blue-plaques/.

• On Now: Garnitures: Vase sets from National Trust Houses. Being run in conjunction with the National Trust, the display at the Victoria & Albert Museum in South Kensington explores the history of ‘garniture’ – sets of ornamental vases unified by their design and a specific context. A status symbol for a period between the 17th and 19th century, garnitures fell out of fashion and complete sets are now extremely rare. The display features garnitures loaned from 13 different National Trust houses as well as objects from the V&A’s collection. Highlights include a garniture made in miniature for a doll’s house, an extremely rate 17th century silver set of jars, a Rococo set and Wedgwood ceramics. The free exhibition runs until 30th April.
