Vrijthof is one of the best known squares in Maastricht, the Netherlands. From 13 to 20 November, it was host to a spectacular 3D projection mapping show, taking the audience back in time. The 20 minute show gave an overview of the turbulent history of the city and was projected onto the façade of the 'Hoofdwacht', a military guardhouse with a history dating back to the 17th century.

AV company Houben Media was responsible for the full technical support of the event. They realized the vibrant projection show with a dual-stack configuration of two Barco FLM HD20 events projectors.
