The annual City of London Festival has a full programme for 2013, promising to animate the Square Mile with an extravaganza of music, dance, art, film, poetry, family and participation events, transforming some of the City’s most iconic venues and outdoor spaces into a wealth of creative activity for everyone to enjoy. Director Ian Ritchie’s final edition, after eight years at the helm, offers an entertaining but innovative programme rooted in three main, interlocking themes: city walls – connecting the City of London with Derry~Londonderry and other historic walled cities from Utrecht to Jerusalem; conflict and resolution; and trees, sustaining the Festival’s artistic responses to the environment. Using the themes as a platform, the Festival will reflect on significant landmark anniversaries. Booking opens on 11th April (priority booking from 4thApril). (t) 0845 120 7502, www.colf.org
