Visitors might be ready to meander unaccompanied by means of the gardens of Queen Elizabeth's London house for the primary time from Friday - and revel in a picnic whereas they're there. There have beforehand been guided excursions of Buckingham Palace's 39-acre grounds, whose present panorama dates again to 1820. But this 12 months a 16.50 pound ($22.70) ticket, accessible till September, will permit vacationers to discover the gardens by themselves.
