This weekend’s a corker: the Paralympic Games have arrived, St Paul’s is open late and Kings Cross is staging a festival with a truly delicious concept.

Summer Lates at St Paul’s Cathedral
Take advantage of extended opening hours and free entry at St Paul’s Cathedral on selected nights during the Paralympic Games. Sir Christopher Wren‘s English Baroque masterpiece tends to invoke hushed awe, so it’s appropriate that the Summer Lates openings are intended for quiet reflection. Guides and priests will be on hand to  explain the cathedral’s history and spiritual life, while organ notes drift around you. The cathedral floor will be open from 6pm until 9pm with a short service at 8.45pm, and the cool underground crypt will be selling “Best of British” refreshments until 10pm.
31 Aug, 3 Sep and 7 Sep

London Live at Trafalgar Square
As the Paralympic Games take the stage in the UK’s sporting summer, BT London Live has moved its site offering free London 2012 celebrations to Trafalgar Square. You’ll be able to try out Paralympic sports like sitting volleyball, wheelchair basketball and wheelchair tennis, chill out to live music or watch coverage of the Paralympics on a giant screen. It’s free entry and unticketed – just turn up.
Until 9 Sep

King’s Cross Ice Cream Festival
The organisers of the King’s Cross Ice Cream festival don’t just want you to eat the cool white stuff. They’re calling on ice cream fans to get hands on with the creative process, from milking a cow at the petting farm to experimenting with the latest nitrogen technologies to whip up some frozen delights. The festival is being held in the new Granary Square in Kings Cross and will showcase the best local ice creams from London and the South East.
1-2 Sep

Bowiefest at the ICA
The first ever festival dedicated to David Bowie’s film career will touch down at the Institute of Contemporary Arts this weekend for screenings, talks and a Bowie themed party on the opening night. Re-aquiant yourself with cult classics from the 1970s and 1980s like Labyrinth, where Bowie played Jareth the goblin king, alongside a cast of puppets from Muppets creator Jim Henson. 
31 Aug-2 Sep

Chelsea AutoLegends
Classic cars will take over Royal Hospital Chelsea‘s grounds on Sunday, as the third Chelsea AutoLegends event brings motoring fever to west London. The bill includes supercar and rally car parades and the chance to meet celebrities like five-times Le Mans winner Derek Bell. One exciting addition is the festival’s new celebration of women in motorsport, fronted by model and race driver Jodie Kidd. Another highlight will be seeing Bloodhound SCC, a car that looks like a rocket with good reason: its team are trying to break the elusive 1000mph speed barrier.
