St. Antoine Church
This is the largest Roman Catholic church in Istanbul. It is located on Istiklal Street which is the longest pedestrian street in the city.
The original church was built in the 18th century for the local Italian community. It was later replaced with the current building which was built by an Istanbul born Italien architect Giulio Mongeri in 1912.
The church also has a lovely courtyard in front where you would see Christmas ornaments in December.
