OPEN GARDENS WEEKEND: London Open Gardens Weekend is a chance to explore the city's green spaces via open days, tours and talks. They range from allotments to small private gardens, to the larger gardens in the likes of Eaton Square, usually only accessible to residents with a key. 6-7 June 2026
LONDON MAP FAIR: The Royal Geographical Society hosts around 40 national and international antiquarian map dealers selling original maps from the 15th to the 20th century, with prices starting from about £10 (and going much higher, if you happen to have deep pockets...). The London Map Fair also features lectures including Rose Mitchell on historic mapmakers and talks by Ashley Baynton-Williams on starting a collection. 6-7 June 2026
BARNET MEDIEVAL FESTIVAL: See re-enactments of the 1471 Battle of Barnet, as well as displays by the gunners, archers and mounted knights, at this year's Barnet Medieval Festival. There's also a medieval-style market, craft displays and an art exhibition, all taking place at Lewis of London ice cream farm, just north of Barnet. 6-7 June 2026
