History buffs and architecture fans may soon be looking for central London hotels as some of the city's most iconic buildings open their doors to the public.
Open House London aspires to be a celebration of the capital's architectural wonders, with hundreds of buildings in and around the city staging tours over September 17th and 18th.
Victoria Thornton, the event's director, commented: "Open House is the annual opportunity for Londoners to get inside London's architecture and see how good design plays an important contributing role in creating and sustaining a 'liveable' city."
According to the director, 89 per cent of last year's participants said the tours were the best way to become more knowledgeable about the capital's architecture.
Many key London landmarks are included in the event's programme, such as the BT Tower, which is applied for by ballot with places drawn at random.
Booking for other locations, such at the Gherkin, is open from August 8th through to September 14th.
Charity-minded visitors can always take part in the London Night Hike, which involves a ten or 20 mile walk though the capital and famous spots, including City Hall, Horse Guards Parade, the Royal Geographical Society and more.
Last year's hike saw 2,000 people turn out to support Maggie's Cancer Centres, raising £400,000 to support the existing network of care homes across Scotland and London.
The free events also include a variety of tours conducted by architects, such as the one taking place in Bermondsey Square, where a representative from East Architects will outline the process they undertook when creating the award-winning public space.
