Trinity Church is a historic parish in the Episcopal Diocese of New York, whose church is located at 89 Broadway opposite Wall Street, in the Financial District of Lower Manhattan in New York City. Known for its centuries of history, prominent location, distinguished architecture and bountiful endowment, Trinity's congregation is said to be "high church", its activities based on the traditions of the Episcopal Church and the worldwide Anglican Communion in missionary outreach, and fellowship. In addition to its main church, Trinity parish maintains two chapels: St. Paul's Chapel, and the Chapel of St. Cornelius the Centurion on Governors Island. The Church of the Intercession, the Trinity Chapel Complex and many other of Manhattan's Anglican congregations were once part of Trinity parish. Columbia University was founded on the church's grounds as King's College in 1754.
