Get yourself feeling ridiculously festive with an evening of carols inside Sir Christopher Wren’s architectural masterpiece, aka The Big Lad aka St Paul’s Cathedral. The legendary London landmark hosts a series of mostly free and unticketed carol concerts each year, alongside a couple of ticketed charity gigs raising money for the likes of Blood Cancer UK and the MS Society. Visit over December for a huge range of concerts, including family-friendly services, a night of Handel’s ‘Messiah’ and traditional carols. The big events to look out for are A Celebration of Christmas (Dec 15) and the Christmas Carol Service (Dec 23 and 24). They’re free and always hugely popular, so get down there early and be prepared to queue. Start practising your high notes now. Full information can be found here.
