London is home to some of the most fascinating sights and sounds in the UK – and next month, you have the chance to take a closer look at some of the city's most impressive buildings, places and neighborhoods.
In September, visitors to the capital are offered the opportunity to dig below London's surface, thereby gaining a deeper understanding of its culture and history.
Through Open House London, tourists will be able to visit more than 700 buildings across the city on September 21st and 22nd.
Be warned, though, that the majority of bookings are on a first-come basis, meaning you haven't got long to plan your itinerary.
The overarching ambition behind the move is to make architecture more accessible to the masses.
"Four buildings are running a ballot for admission through Open House. These are: 10 Downing Street, The View from the Shard, EDF Energy London Eye and Gray's Inn," Open House London explains.
"Remember: the ballots will be open until Friday September 13th."
However, it's important to acknowledge that there are plenty of other great things to see and do as part of the Open House experience.
So, when you are next in London, be sure to enjoy some of the impressive architecture on display throughout the city.
Elsewhere, one of the most popular landmarks in London is St Paul's Cathedral, which is open to the public for a fee and remains an iconic sight.
Designed by Sir Christopher Wren, the cathedral is among the most famous in the world and is a must-see landmark for any first-time visitors to the UK capital.
On the south side of the river, meanwhile, is the Shard, which is one of the dominant features of the London skyline.
Completed in 2012, the impressive-looking structure is home to a nice restaurant, while there is also a viewing deck for the public near the top of the building.
