London’s grand building plans that never went ahead are the subject of a new exhibition opening at the Guildhall Art Gallery tomorrow. The London That Never Was imagines a city where the Tower Bridge is clad in glass and where a colossal burial pyramid looms over Primrose Hill. The free exhibition can be seen until 8th December. For more, head here. (To see some of the projects that were never built, see our previous series, 8 structures from the London That Never Was).

A new garden celebrating the evolution of plants has opened at the Royal Botanic Gardens, Kew. The Agius Evolution Garden is divided into eight sections to form “garden rooms” with each room containing closely related plants, revealing fascinating stories such as the connection between strawberries and nettles and why the Asteraceae family have “false flowers”. Admission charge applies. For more, see www.kew.org.

The property, known as Number 1, London, is one of 12 initially being profiled in depth in a pilot project on the new English Heritage online resource, Portico. Others include Down House, the former home of Charles Darwin, located in Kent, as well as Beeston Castle, Brough Castle, Byland Abbey, Carlisle Castle, Dunstanburgh Castle, Easby Abbey, Kenilworth Castle, Lullingstone Roman Villa, Rievaulx Abbey and Wroxeter Roman City near Shrewsbury.

The West Lawn of the British Museum Forecourt has been turned into an image of the Australian continent as part of a five year partnership programme between the museum and the Royal Botanic Gardens, Kew. The landscape moves from the vegetation of the eastern Australia’s coast through to the red centre and onto a rocky Western Australian outcrop. It showcases some of the continent’s unique and highly threatened flora. The  construction of the landscape, which follows one showcasing that of South Africa last year, is part of the museum’s ‘Australian season’. Runs until October. Admission is free.

• Dame Judy Dench was awarded the Freedom of the City of London for services to acting at a ceremony at the Guildhall last week. The winner of an Academy Award, nine BAFTAs and three Laurence Olivier Awards, Dame Judy is an icon of stage and screen. She is reportedly looking forward to driving her sheep over London Bridge and occasionally wearing a sword in public – both privileges of those awarded the Freedom of the City of London. The Freedom of the City’s origins are believed to date back to 1237 and enabled recipients to carry out their trade. Today people are nominated for or apply for the Freedom for the link with the City or are awarded it for a significant contribution to London life. Many of the traditional privileges – such as driving your sheep over London Bridge or being hanged with a silken rope – no longer exist.
