It's got to be one of London's best-loved events: from the arrival of the eagerly awaited annual catalogue and the feverish planning of visits, to that autumn weekend when the city flings open its doors to citizens and visitors. Yup, it's Open House - time for Londoners to get up close and personal with buildings they normally can't access.

What a treat it was to inspect gas lamps around Westminster last November with Ian and Garry from British Gas, who love their lamps. They clean and polish them, feel pain when one gets smashed by a passing truck and complained to the Royal Parks who repainted lamps in St. James’s Park without gold paint. Lamps are listed by English Heritage so if one gets knocked down, it must be replaced with an exact copy.  Below are some more interesting facts as shared by Ian & Garry while on this education and training tour for Blue Badge Tourist Guides.
