Do some late-night meat bartering at Smithfield Market

The city’s centuries-old meat market is pretty nice to gawp at any time of day with its ornate arched ceiling and zany colour scheme (white, purple, blue and green). But, it’s not until the middle of the night that the place really comes alive. Between 2am and 9am, the market is a hubbub of meat vendors. Forget late-night meat sweats, here you can go late-night bacon bargaining and ham haggling till the early morning.

Pull an all-nighter at Prince Charles Cinema

Can you even call yourself a film buff unless you’ve sat through all 20 hours and 10 minutes of ‘Star Wars’, or prised your dry, bloodshot eyes away from Aragorn’s coronation at 3am? The answer is no. And no one throws an all-night film marathon quite like London’s wild card cinema. Whether it’s a 12-hour Disney sing-along or an all-night sci-fi medley with director’s commentary, Prince Charles Cinema probably hosts it. Unfortunately, there’s no all-nighter planned for Solstice, but there are loads of festive films being screened after dark.

Gaze at the stars

London may be a hive of light pollution, but there are still some dark pockets where you can gaze at the stars. Nestled away from the bright lights at the edge of the capital, Morden Park Hall is a well-known stargazing spot. The former deer park is blessed with a large open meadow, which is perfect for peering at those faraway rocks. If you’re new to star-seeking, why not join The Baker Street Irregular Astronomers who put on regular free stargazing events.

See Tower of London’s covert Key Ceremony

Every evening at 9.30pm a bunch of Yeoman Warders (aka Beefeaters) gather outside the Tower of London and shout ‘Halt, who comes there?’ into the darkness. This is the Ceremony of the Keys and it’s taken place every day, without fail, for 700 years to ‘lock up’ the Tower. You can nosey in on this bizarre tradition yourself and get a late-night look at the ancient fortress. It’s free to head along, but must be pre-booked. It’s also pretty popular and can sell out up to 12 months in advance. So get booking quick to grab the next available slot.

Creep yourself out on a ghost walk

Give yourself the heebie-jeebies by prowling through London’s dark streets on an evening ghost walk. London Ghost Walk’s nighttime Christmas tours will lead you through the gloomy alleyways of the old City where you’ll unearth plenty of ghosts of Christmas past, including a demon hound that once lurked in an ancient church tower and the place where the ‘Hellfire Club’ came into being.

Bop along to some late-night jazz

Opened in 1959, Ronnie Scott’s is a legendary Soho institution sure to get any jazz fanatic more than a little hot under the turtleneck. It’s also open every evening until 3am for the ‘Ronnie Scott’s Late Late Show’. The nights have showcased  Stevie Wonder, Robert Glasper, and Lady Gaga, and in true improv style, any top-notch performers in town are invited to drop by, meaning the programme can change last minute. If you want to live out any Kerouacian dreams, this is the place to do it.
