毛里茨伯爵死后将这座房子捐赠给市政府，但是1821年才成为皇家美术馆。莫瑞泰斯皇家美术馆的收藏有许多15-18世纪佛兰德(Flemish)派和荷兰派的画作，很多的作品式来自于前荷兰王子威廉五世的收藏(William V of Orange)。馆中较著名的画作包括有：扬·弗美尔（Johannes Vermeer）的《戴珍珠耳环的女孩》（The Girl With The Pearl Earring）、伦勃朗（Rembrandt van Rijn）的《杜尔博士的解剖课》(Anatomy Lesson of Dr Tulp)等等。
Welcome to the Mauritshuis! The Mauritshuis is home to the Best of Dutch painting from the Golden Age.
