A London gallery has been named the world's best hidden gem

London is a city with some major world-famous attractions as well as numerous hidden gems you might not know about – so much so that we wrote a whole guide about them. Budget airline Wizz Air have done the work to uncover the greatest hidden gems all over the world and a London art gallery came in at the top spot. 

The Wallace Collection in Marylebone has been named the world's number one hidden gem in the rankings, beating off competition from unusual sites in places like Paris and Amsterdam. Rankings were determined by looking at each place's reviews on TripAdvisor. The gallery has more than 6,500 reviews on TripAdvisor, with an overall score of 4.5 and well over 500 reviewers describing it as a hidden gem. 

Visit for yourself and you can see thousands of paintings by some major names like Titian, Rubens, Gainsborough, and Velázquez. Antique furniture and other decorative pieces from the collection of Sir Richard Wallace and the Marquess of Hertford are also on display. There's a restaurant on-site as well. After you've visited The Wallace Collection, our guide to London's secret places will help you find even more unusual places to go.
