• A social reformer, a former slave turned campaigner and the “people’s princess” are among six women who will be commemorated with new English Heritage Blue Plaques this year. The first of the new plaques – dedicated to crystallographer and peace campaigner Kathleen Lonsdale – was unveiled last week at the home in Seven Kings, Redbridge, where she lived from 1911 to 1927 during her early days at UCL and the Royal Institute. Lonsdale went on to carry out ground-breaking work on crystal structures and played what’s described as a “fundamental role” in progressing x-ray crystallography. Other plaques will commemorate social reformer Caroline Norton, designer Jean Muir, former slave and campaigner Ellen Craft, barrister Helena Normanton, and, Diana, Princess of Wales.

• The garden at Buckingham Palace will open to the public this summer, allowing visitors to explore the 39 acre grounds on a self-guided tour for the first time. The route will encompass the 156-metre herbaceous border, plane trees planted by Queen Victoria and Prince Albert, and take in views of the garden’s 3.5 acre lake and island with its beehives. Visitors will also have the chance to enjoy a picnic on the lawns and explore the south-west of the garden – which includes the Rose Garden, summer house and wildflower meadow – on guided tours. Meantime, during April and May enthusiasts are able to enjoy the garden in springtime on guided tours. And for those unable to make it in person, a series of digital talks, A Warden’s Welcome, which explore Buckingham Palace, Windsor Castle and the Palace of Holyroodhouse kick off online next Wednesday. Charges apply for all – for more information and tickets, see www.rct.uk.
