Manhattanites were proud of their churches and synagogues, and there were a lot of them. Every Christian denomination of the time, and more than one kind of Judaism, was represented. There were also scores of missions and charitable organizations attached to the various denominations. I haven’t been able to find evidence of any other religious groups, but they may well have been there. Certainly the large Chinese population may have had some organized approach to religious services.
The relative importance of any particular denomination or church or temple is a matter of opinion. The size of the congregation and their economic power, the age of the institution and its location, all of these factors and others would have to be taken into account to come to any conclusions. This is not something that interests me particularly as an author, but I can provide information on those institutions which are relevant to The Gilded Hour either in the plot or setting.
Trinity is an Episcopal Church located at the corner of Broadway and Wall Street Trinity Church is located at the intersection of Broadway and Wall Street in downtown Manhattan. St. Paul’s Chapel is part of the Trinity parish.
The first Trinity Church building, a modest rectangular structure with a gambrel roof and small porch, was constructed in 1698. According to historical records,Captain William Kidd lent the runner and tackle from his ship for hoisting the stones.
Anne, Queen of Great Britain, increased the parish’s land holdings to 215 acres (870,000 m2) in 1705. (Wikipedia)
The second Trinity Church was damaged in a snow storm and torn down. The third and current Trinity Church began construction in 1839 and was finished in 1846. In 1883 Trinity’s 281-foot spire was the highest point in the city. It retained this record until 1890 and the construction of the New York World Building.
St. Patrick’s Cathedral
was built over a long period of time and consecrated in 1879. The cathedral, which was designed as the seat of the archbishop, had the same name as the earliest Roman Catholic Church, which stayed where it was in one of the poorest neighborhoods. It took years to complete all the structures associated with the Cathedral — the seat of the archbishop wasn’t completed until 1882, for example. In 1883 the cathedral sat across from the Vanderbilt mansions, which were all torn down over time. It now faces Rockefeller Center and the Atlas Statue.
Old St. Patrick’s Church on Mott Street was also surrounded by related institutions, some of which were a home for unwed mothers, a lying in hospital, and orphan asylums.
St. Anthony of Padua
Was built specifically to meet the needs of Italian immigrants. It stood at 149 Sullivan Street until funds could be raised for a larger church to serve the growing immigrant population. Construction began on the new church in 1886, after the events of The Gilded Hour.
