During the night of the 25th of July (from 20h to 23h) the Museum closed its doors trapping 20 youngs inside with only one possibility to survive: solve six riddles and unlock a padlock which allowed them to reopen the Museum’s doors. The participants had to solve misteries and trap questions related to the paintings and the painters who created them. After three hours, all the public finished the quizzes and were able to return to their homes knowing a little bit more about the secrets of our masterpieces. The activity, organized to celebrate the festivities of Escaldes-Engordany, was very successfull and its positive result leads the Museum to think about new editions.
