Just above Gellért Square, as you start heading up towards the top of Gellert Hill, there’s a sort of rock balcony. The balcony leadsto a little chapel carved into the rocks of the hill; at the back of the chapel (which means deep inside the rock) there’s a door: open it and see a truly amazing rock chuch. It was built in 1931 – only to be closed and walled-up 20 years later by the communis Regime. As soon as it fell (1989) the church was re-opened and made it functional again.
