This is the 15th time the annual event has been held, and the programme includes special events, art talks and guided tours.
124 museums in Vienna will participate, including this year the Fisheries Museum and the Stephansdom cathedral museum.
Some fun events for adults include the chance to take part in a pot holder crochet competition in the Furniture Museum and learn how to kiss a lady on the hand at the Emperor Franz Joseph Hat Museum.
The Esperanto Museum in the Austrian National Library will offer Klingon language courses so you can learn to communicate with your favourite character in the cult series Star Trek.
250 museums across Austria will offer special activities for children.
The event is sponsored by the Austrian National Broadcaster (ORF). Seven museums in Switzerland will also participate this year, helping give the event some international flair, according to ORF general director Alexander Wrabetz.
The Lange Nacht ticket can be purchased both at the ‘Treffpunkt Museum’ on Vienna's Heldenplatz and at the individual museums themselves. To mark the anniversary every 15th ticket bought as part of a group booking will be free.
Tickets cost €13 in Vienna and €6 in the regions, and grant access to all participating museums from 6pm to 1am. The price includes the use of shuttle buses between the museums and public transport in Vienna.
Tickets are also available in advance at ORF.at. Entry is free for children up to 12 years of age.
