What's the attraction?
Who wouldn't want to poke around a museum after dark? As night falls, it's easy to let your imagination run wild, imagining the exhibits coming to life as you wander through dimly lit halls of Egyptian mummies, past towering dinosaur skeletons (remember Ben Stiller in Night at the Museum?).
The first Lange Nacht der Museen took place in 1997 in Berlin, the first Nuit des Musées in France in 1999, spreading out across Europe in 2005 to become the European Night of Museums. Last year, two million visitors in France alone enjoyed the special events, temporary installations and dramatic performances at venues across the country.
This year, on 18 May, the programme, backed by Unesco, will unfold across more than 30 countries across Europe (nuitdesmusees.culture.fr).
In the UK, you get three nights for the price of one (16-18 May; culture24.org.uk). Last year, more than 530 venues got involved in the event. This year looks set to be even better: new venues taking part include the Golden Hinde galleon in London and Manchester's new National Football Museum. Highlights include an all-night poetry workshop at the Writers' Centre in Norwich (01603 877177; writerscentre norwich.org.uk; £65) and a free 1920s murder-mystery performance at Blackwell The Arts and Crafts House in Cumbria (015394 46139; blackwell.org.uk; booking essential).
Not everyone toes the date-line. Those doing their own thing include Sweden. Stockholm's annual Culture Night (kulturnattstockholm.se) takes place this coming Saturday from 6pm until midnight and offers free admission to more than 100 events at more than 85 art galleries, clubs, museums and theatres, including boat rides around the archipelago.
In Switzerland, Geneva's Museum Night is on 11 May. The tourist board has a special offer of one night's accommodation, a Museums at Night ticket (there are 21 places flinging open their doors until midnight and a host of additional activities) and a free public-transport card for Sfr68 (£48)pp, when booked online at geneve-tourisme.ch. Flights extra.
At the Paul Dupuy Museum in Toulouse there will be readings of the works of Villon, Ronsard, Rimbaud and Verlaine on 18 May (00 33 5 61 14 65 50; bit.ly/PaulDupuy; toulouse-visit.com), while elsewhere in France highlights include a film screening in the Vesunna museum in Aquitaine on Heroes and Mythology (perigueux-vesunna.fr). The Grenoble Museum will dedicate its night to the artist Giacometti (museedegrenoble.fr), and the Jean Cocteau Museum in Menton, will put on performances of the poet's favourite jazz (nuitdesmusees.culture.fr).

Not only will there be guided tours during the night in the tropical greenhouse, but children can bring a sleeping bag and bed down in the House of Insects. Evening activities cost €10 or €18 including an overnight stay and morning walk in the woods.
Wake up and smell the coffee
The Age of Discovery is the theme of Museum Night celebrations in Povoa de Varzim's town museum in northern Portugal (cm-pvarzim.pt; €20). In this traditional seafaring and shipbuilding town near
Porto, a vivid historical re-enactment is scheduled from 7pm until midnight, when the museum will be invaded by sailors, navigators, merchants, pilgrims and soldiers. The air will be scented with freshly brewed coffee, chocolate and spices brought back by the explorers. There will be a dinner in the courtyard, as well as music, dancers and jugglers.

"This year, the festival starts on a Thursday night. I am really looking forward to an event at the Bristol Museum and Art Gallery, where Gavin Turk will take visitors on a magic-carpet ride. Museums at Night has 10 artist-led events this year, each with its own unique quality akin to creative alchemy." Nick Stockman, project director of Museums at Night in the UK

Who said that?
"In poetically well-built museums, formed from the heart's compulsions, we are consoled not by finding in them old objects that we love, but by losing all sense of Time." from 'The Museum of Innocence' by Orhan Pamuk
"In museums and palaces we are alternate radicals and conservatives." Henry James
"We used to build temples, and museums are about as close as secular society dares to go in facing up to the idea that a good building can change your life (and a bad one can ruin it)."Alain de Botton
