Maulbertsch frescoes in the upstairs Reception Hall at the Baroque Bishop’s Palace, built in 1783, miraculously survived the WWII air raids, but are not usually open to the public. You can, however, admire the murals of Roman ruins and gods painted in 1784 by István Dorffmeister in the Sala Terrena on the ground floor. Other rooms contain photographs of the cathedral before and just after the bombing of WWII and the Diocesan Collection and Treasury, including missals and bibles from the 14th to 18th centuries, Gothic vestments, a beautiful 15th-century monstrance from Kőszeg and even a bejewelled replica of St Stephen’s Crown made in the USA.
