#Museumweek is a week-long global Twitter campaign mobilising museums and their visitors around the globe. The 2016 edition will be taking place from 28 March to 3 April.

The principle is very simple: 7 days, one theme and hashtag per day. See each day's hashtag in the attached document.

Registration now open - it only takes two minutes to fill in the form.
