Heart Beat, Covent Garden, central London

The work of French artist Charles Pétillon, the 54-metre long Heart Beat installation in Covent Garden features 100,000 white balloons, illuminated by pulsating white light. Pétillon says the goal is to draw attention to Covent Garden's role as the beating heart of London.

Palace Street, central London

Only a stone's throw from Buckingham Palace, a block of houses in an elegant Victorian terrace on Palace Street are boarded up and in sore need of some tender loving care. Next to Westminster City School, these four-storey blocks still have ornate green wrought iron balconies and railings. Further down the street is the Cask and Glass, a characterful and compact Shepherd Neame pub with tables in the sun.
