St. Peter's Church is a Roman Catholic Parish located in Plattsburgh, NY in the Champlain valley. The church was originally built by the Canadian-Catholic community in 1853. Fr. J.P. Bernard set out from Montreal for Plattsburgh with $9.00 and a plan for a new church in his pocket. On September 5, after a meeting with five newly appointed trustees, Fr. Bernard began construction of the French speaking parish. The next day Fr. C.F.M Sallaz O.M.I. arrived to assist Father Bernard. During the construction of the church building, the parish community rented a vacant brick building on Oak St. where they held their worship services. The first marriage announced to the parish took place October 30, 1853 and the first Baptism announced to the parish took place on June 6, 1853. To answer financial needs of the newly built church, the first Bazaar was held on December 19, 1853. The blessing of the Sacristy took place on February 4, 1855 followed by the first Mass. The first recorded high Mass took place on March 2, 1856. In response to the parish's growth, on November 19, 1865, the Bishop of Albany, Msgr. John Conroy blessed the church building in the presence of the Oblate Fathers. This marked the beginning of the church of St. Peter's that is present today. Since it's early history, St. Peter's has continued to grow in many different areas such as renovations, community outreach, and social ministries.
Today, the church of St. Peter is a Roman Catholic Parish of the Diocese of Ogdensburg with over 1800 families. The parish offers a range of Social Ministries, Programs for Christian Formation, Liturgical Ministries, Special Events, and Services to the Community.
