This is central Frankfurt's oldest Roman Catholic parish church, and in 2019 it celebrated the…read more800th anniversary of its establishment, in a reopening ceremony following a renovation project that lasted almost a decade. As of 2022, it's open weekday afternoons/evenings for visits from 3 p.m. to 7 p.m. and, except for Mass times outlined below (when touristic visits aren't allowed), open Saturdays and Sundays from 11 a.m. to 6 p.m.
On Saturday evenings, the English parish holds its Vigil Mass at 6 p.m. and on Sundays, the German parish holds Mass at 11:30 a.m. and the French community holds Mass every other Sunday evening at 6 p.m. The English parish also currently holds a weekday evening Mass at 6 p.m. Tuesdays.
Note that due to local regulations to prevent the spread of Covid-19, you must wear a mask at all times while in the building and, before entering church for a weekend Mass, you must show German "3G" documentation indicating that either you're fully vaccinated, have fully recovered from having Covid-19 with a test showing virus antibodies or have had a negative test for the coronavirus within the last day. (This applies only to the Saturday and Sunday Masses).
