St. Stephen's Cathedral

The Stadttempel is the main synagogue in Vienna. It was built between 1823 and 1826 behind a trivial five-storey apartment building. According to the regulations in force at the time, non-Catholic places of worship had to be "hidden" and not visible directly from the street. On the night of the November 1938 pogrom, the main synagogue was the only one to escape destruction because of its narrow residential area. However, the interior was devastated and misused as a collective camp for Viennese Jews. A commemorative plaque in the entrance hall was unveiled in September 1988.

The Michaelerkirche (St Michael's Church) is one of the oldest churches in Vienna. It was built in the 13th century. It is a rare example of a Romanesque church in Vienna, although with baroque and classical additions.

The Greek Church of the Holy Trinity is located in the old "Greek Quarter". Inaugurated in 1858, the building has a distinctive Byzantine style.
