On the roof of the tavern The 3 Stags in Lambeth, Dr Luke Dixon is practicing his summer activity: urban beekeeping. "London is the ideal place for honey because of the great variety of flowers and parks and its mild climate." He told the BBC, "There are hives at Lambeth Palace in Regents Park, and even the queen has had hives at Buckingham Palace". Dr Luke Dixon is an expert in urban beekeeping. "Apiculture in the city is not new. People have been keeping hives on London's rooftops for decades. Robin Leigh-Pemberton, a governor of the Bank of England, has kept hives on the roof of the bank on Threadneedle Street and others have discreetly done the same thing on buildings and offices out of the public gaze."
