This Week in London – #LondonUnited; Westminster Abbey watercolours; and, celebrating ‘numismatics’…

The anniversaries of the four terrorist attacks which took place in London last year – in Westminster, at London Bridge, Finsbury Park and Parsons Green – are being marked from today with a 3D installation on the map area at City Hall. The public are able to pay their respects by signing a digital “book of hope” and interacting with the installation by sending messages of strength, hope and resilience using #LondonUnited on social media, with the messages then projected onto a map of London that #LondonUnited will stand on. The installation, which opens today on the anniversary of the Westminster attack, will remain open until 19th June, the anniversary of the attack in Finsbury Park. Further ‘London United’ exhibitions are also planned for later in the year. “These were not only attacks on our city and our country, but on the very heart of our democracy and the values we cherish most – freedom, justice and tolerance…” said Mayor of London Sadiq Khan. “I hope these arrangements will help people to come together and remember those who were killed and injured, to show solidarity and support for their families and friends and the people whose lives have been affected by these tragic attacks. As we enter this period of remembrance and reflection, we stand together as Londoners, united against terrorism and in hope for the future.” The installation will be open from 8.30am to 6pm Monday to Friday, except Bank Holidays. The Westminster attack anniversary is also being marked today with the projection of the phrase #LondonUnited on the Houses of Parliament from dusk until midnight. Further projections will take place on the anniversaries of the other attacks at the sites where they took place. Londoners who may need support, can visit victimsofterrorism.campaign.gov.uk or call 0808 168 9111.

A series of watercolour paintings depicting the interior and precincts of Westminster Abbey have gone on display in the abbey’s chapter house. The paintings, by internationally acclaimed British artist Alexander Creswell, represent, in the words of the Dean of Westminster, the Very Reverend Dr John Hall, “the first time ever a large suite of paintings has been commissioned to capture the stunning architecture and amazing light of the Abbey”. They can seen until 16th May. Entrance to the chapter house in the Abbey’s east cloister is free. For more, see www.westminster-abbey.org/events/events/glimpses-of-eternity. Meanwhile the abbey announced last week that there will be a special service of thanksgiving later in the year for the late theoretical physicist Professor Stephen Hawking, who died on 14th March at the age of 76, during which his ashes will be interred near the grave of Sir Isaac Newton.

Numismatics – the study of coins, medals, banknotes and associated objects – is the focus of a new exhibition opening at the British Museum today. Money and Medals: mapping the UK’s numismatic collections celebrates the work of the Money and Medals Network, which provides advice to British museums, and features objects from six participating institutions. They include a framed set of replica Greek coins dating from the late 19th century, a ‘Magic Money Machine’ which can seemingly transform a roll of blank paper into banknotes, a set of medal miniatures from Henry Hook, who won the Victoria Cross for gallantry at the Battle of Rorke’s Drift, and a selection of Roman coins and replica medals of Louis XIV from the collection of the Armagh Robinson Library, founded by Archbishop Richard Robinson in 1771. The exhibition, which is free, can be found in Room 69a and runs until 30th September. For more, see www.britishmuseum.org.
