After roughly four years of restoration works, the Majorat House of the Princes von und zu Liechtenstein in Vienna was reopened on 9 April 2013. The staterooms of the Liechtenstein City Palace will in future also be accessible to the public. Alongside the staterooms, the new use includes the LGT Bank premises and a three-storey art depot that was lowered below the inner courtyard during the conversion work; in addition, there are also rooms that are available to the Princely family during their stays in Vienna. Not only is the restoration of significance from a cultural policy point of view, it is also of considerable importance for monument conservation in Europe. It is the largest completed restoration in the City of Vienna to apply scientific monument-conservation principles, and is beyond doubt already to be regarded as the standard for the restoration of similar buildings in Europe. The restoration has been honoured not only by the City of Vienna; the conservation project related to the Liechtenstein City Palace also received a special mention by the EU in the form of the Europa Nostra (the voice of Cultural Heritage in Europe) in 2014 and the German Light Design Award 2014 in the museums category.
