The Inner City Parish Church (Belvárosi Plébaniatemplom), located next to Elizabeth Bridge, is the oldest church in Pest. Founded in 1046, it bears witness to various architectural styles. Underneath the baroque façade and the gothic walls are the remains of a Romanesque basilica, built in the 12th century.
The square next to the church exposes some Roman ruins, the remains of Contra-Aquincum. The fort was built as an outpost of Aquincum.
