St. Michael's Church (German: Michaelerkirche) is a church in Vienna, Austria. It is a Roman Catholic church and is one of the oldest churches in the city. The church is named after Saint Michael, an important angel for Roman Catholics. It was built between 1220 and 1240 in the Romanesque style.
Many changes have been made to the church over the years, both inside and outside. The steeple was added in the 16th century. The church's facade (the outside front of the building) was changed to a neo-classical style in 1792. The facade has not changed since then.
