Located a few steps north of Ruprechtsplatz, Ruprechtskirche dates from about 1137 or earlier, giving it the honour of being the oldest church in Vienna. The lower levels of the tower date from the 12th century, the roof from the 15th century and the iron Renaissance door on the west side from the 1530s.
What makes this church attractive in summer is its unusually simple exterior of ivy-clad stone walls in cobblestoned surrounds. The interior is sleek and worth a quick viewing, with a Romanesque nave from the 12th century.
