Nagyboldogasszony-székesegyház
A short walk from Vác’s main square, this 18th-century cathedral is an outstanding example of Hungarian neoclassicism. It was built between 1763 and 1777 by Archbishop Kristóf Migazzi to the designs of the Italian architect Isidor Carnevale; the most interesting features are the murals by the Austrian Franz Anton Maulbertsch, both on the dome and behind the altar. Exquisite frescoes decorate the walls inside. Due to break-ins, you can view the interior only through a locked gate, except during the twice-daily masses.
