St Peter's, the first Roman Catholic parish in New York, was established in 1785 on the site it now occupies, predating the first Bishopric in the United States, founded in Baltimore, Maryland, in 1789. The present church exterior was completed in 1840 and was ultimately declared a landmark by Federal, State and City agencies.

The Church of St. Vincent Ferrer is a Roman Catholic parish in the Upper East Side of Manhattan, New York City.

The current Saint Thomas Church is actually the fourth church for the parish. The third church, which was also at the current site at Fifth Avenue and Fifty-third Street, suffered a devastating fire in 1905. The first worship service in the current church was on October 4, 1913.

Widely known as St. Bart’s, the iconic church with its distinctive dome is recognized for its inclusivity and tradition of "radical welcome." St. Bart's is located on Park Avenue and 50th Street in New York City.

When the exciting new building was consecrated in 1977, it became known as a welcoming place.

It is a place for all , a majestic rock, a sanctuary of light, a surprise on  Lexington Avenue.
