Church of Our Lady, Parish church in Aschaffenburg, Germany.

Unsere Liebe Frau is a Baroque hall church built from 1768 by Franz Boccorny, with its main altar to the south. The 42 m medieval tower stands on the east side, topped by a slender dark spire. The pale plaster facade rises above a pinkish-red banded base, and the salmon-painted entrance bears the word "STADTTHEATER". Inside, a barrel-vaulted ceiling carries Hermann Kaspar's 1965–1967 fresco.

A church is documented here as early as 1183, and a Romanesque tympanum bearing the name of Archbishop Konrad von Wittelsbach is kept inside. The 42-metre tower dates from the late 13th century. After the old church was demolished, Franz Boccorny built the present hall church from 1768, financed by pastor Christian Stadelmann; it was consecrated on 3 September 1775.

The second bell, dedicated to St Joseph, has rung as the "Verirrtenglocke" (lost-ones bell) since 1958 at 9 pm, or 8 pm in winter. It continues a bequest confirmed by Archbishop Konrad of Mainz in 1186, when a bell on the market tower guided people lost in the surrounding forest back to the city.

The church welcomes visitors during daylight hours through its entrance on Schloßgasse 13. Religious services are held regularly throughout the week, allowing guests to plan their visits around the schedule.

The tower holds four bells. The second, dedicated to St Joseph, has always rung as the "Verirrtenglocke" (lost bell): since 1958 it sounds again at 9 pm, or 8 pm in winter, continuing a foundation confirmed by Archbishop Konrad of Mainz in 1186 to guide people lost in the woods back to the city. The two middle bells were cast in 1746 by Georg Christoph Roth in Mainz.
