Discover London's secret gardens over this weekend of viewings and openings
In 2015 more than 200 gardens not ordinarily open to the public will unlock their gates for a weekend to take part in this annual event, held in association with the National Trust. Spanning 27 boroughs, the gardens take in all sorts of spaces, from traditional squares to roof terraces and allotments, as well as gardens belonging to historic buildings, schools, shops and cafes.
There are 23 gardens taking part for the first time this year, including the churchyard of grade I-listed medieval church St Olave, the All Saints Vicarage Garden which was part of Fulham Palace until 1935 and The Arvon Road Allotments, which are terraced along the railway freight line near Finsbury Park.
Some participating venues may only be accessed when booked onto a free tour – snap up your place when booking your weekend ticket to make sure you don't miss Highbury Stadium Squares, The River Café and Barbican Station Pop-Up Garden. 10 Downing Street is on the list, too, but if you'd like to visit our PM's back yard you'll need to enter a separate ballot (no purchase necessary) to be in with a chance of claiming just one of 40 places.
Walking and cycle tours taking in several venues will help you make the most of your time and see as many gardens as possible. Refreshments will be on sale at some gardens, while at others you'll be able to meet the gardeners. One ticket allows entry to all venues over the weekend.
