Uncover London’s secrets this autumn

Ever wondered what goes on underground, or fancied discovering the secret abandoned stations that used to be a mainstay on the tube map? Bag yourself a ticket for one of London Transport Museum’s tours and delve into London’s forgotten past – from Winston Churchill’s secret Down Street war bunker to Euston’s labyrinth of lost tunnels. And that’s not all: on October 11, London Transport Museum will launch a new 'Hidden London' exhibition at its Covent Garden HQ. You'll be able to spy rare archive photos and posters and secret diagrams from disused stations on display for the first time.
Tour: Various venues and times. Tickets from £35.
Exhibition: London Transport Museum. Tickets from £16.50, kids free. Tickets allow unlimited daytime entry all year.

It may surprise you, but in a small park off Brixton Hill lies London’s last working windmill. Although more than 200 years old, the Grade-II listed tower was left dormant between 1934 and 2011, when it underwent a major restoration. When you visit this slice of the countryside in south London, it’s possible to take a free guided spin of the windmill and to learn all about its history.
Tour dates vary. Free.
