• The Museum of London will next week launch its annual community and training dig at Syon Park in Hounslow. The dig, which will be open to school and community groups, will run from 25th June to 7th July and will focus on the area of Sir Richard Wynne’s house. A Parliamentarian, in 1659 he was implicated in a Royalist insurrection and was imprisoned. The house, which featured in the Battle of Brentford when Royalist troops advanced on Parliamentary forces in London in 1641, was later purchased by the Duke of Northumberland and demolished to extend Syon’s parkland.

• We couldn’t resist mentioning this one: Westminster City Council has released a top 10 list of the strangest objects people have dumped on London’s streets. They include an inflatable Margaret Thatcher and other inflatable dolls, wedding dresses, stuffed animals and a range of film props. The council say that, on average, enough litter is picked up off Westminster’s streets every two days to fill the entire 864 cubic metres of Marble Arch. They add that if just half of the annual waste collected off the street is recycled properly in the correct bins it would save them nearly £1million.

• On Now: Writing Britain: Wastelands to Wonderlands. The major summer exhibition at the British Library, it explores how the last 1,000 years of English literature have been shaped by the country’s places. The exhibition  features more than 150 works with highlights including John Lennon’s original lyrics for The Beatles’ song In My Life, JK Rowling’s handwritten draft of Harry Potter and the Philosopher’s Stone, JRR Tolkein’s original artwork for The Hobbit and original manuscripts from the likes of Jane Austen, William Blake, Charlotte Bronte, Arthur Conan Doyle, JG Ballard and Charles Dickens.
