Dug in 1824, around the same time that Esztergom’s basilica was started, the Dark Gate is tunnel built to link the seminary with the canonical houses.
The passageway is 90 metres long and has a Neoclassical style, with a barrel vault.
It was totally renovated in 2006 and contrary to its name is now brightly illuminated.
The Dark Gate opens onto the archdiocese’s wine cellar, and you can use the tunnel to get from the Seminary to the centre of Esztergom
