• The world of mushrooms is explored in a new exhibition opening tomorrow at Somerset House. Part of the Charles Russell Speechly’s Terrace Rooms Series, Mushrooms: The art, design and future of fungi is curated by writer Francesca Gavin and features works by more than 35 artists, designers and musicians in an exploration of “the rich legacy and incredible potential of the remarkable organism, the ideas it inspires in the poetic, spiritual and psychedelic, and the powerful promise it offers to reimagine society’s relationship with the planet, inspiring new thinking around design and architecture”. Highlights include watercolours by renowned author Beatrix Potter (one of which is pictured), American artist Cy Twombly’s quasi-scientific portfolio Natural History Part I, Mushrooms (1974), and a spectacular floral display, featuring mushrooms grown in Somerset House’s former coalholes, by the London Flower School. The free exhibition, which runs until 26th April, is accompanied by a series of events.

• A newly commissioned film which reimagines Tower Bridge as a musical instrument is at the heart of a new exhibition which opened in the bridge’s Victorian Engine Rooms this week. Created by internationally acclaimed artist, inventor and filmmaker Di Mainstone to mark the bridge’s 125th anniversary, Time Bascule draws inspiration from Hannah Griggs, one of the first women to work at the bridge (in her case as a cook for the Bridge Master and his family between 1911-1915). The display also includes behind-the-scenes footage, storyboards and early sketches, as well as the opportunity for visitors to play a range of specially created musical instruments. Runs until March. Included in admission to the bridge. For more, see www.towerbridge.org.uk.

• Dante Gabriel Rossetti’s Pre-Raphaelite masterpiece, La Ghirlandata, is being unveiled at the Guildhall Art Gallery today following a year-long restoration. William Russell, Lord Mayor of the City of London, is unveiling the portrait which was painted in 1873. Conversation work undertaken included cleaning the painting to reveal a “brighter, fresher scene with a cooler tonality”, repairing and cleaning Rossetti’s original frame, and replaced the deteriorating living canvas. The restoration was made possible thanks to a grant from the Bank of America.
