Have a sleepover with history and spend the night in museums! On June 23, museums open their doors to visitors both in Budapest and in the countryside until 2:30 am for this annual event, which celebrates its 16th anniversary this year. There will be more than 1,000 programs offered at some 100 locations within the capital, all of which can be visited with one single ticket in the form of an armband. In addition, visitors with armbands are entitled to use the Museum Bus, which will run between venues.
