Trinity Church is an Episcopal church located in the center of Boston's Back Bay on Copley Square. It is home to a vibrant parish founded before the American Revolution. Established in 1733, the church is a masterpiece of the American architect, H.H. Richardson. The church is a member of the worldwide Anglican Communion and stands as a cherished landmark at the heart of Boston. The present church was constructed when the great fire of Boston had gutted the second Trinity Church building in 1872. Trinity Church is similar to the Old South Meeting House, which is also associated with Boston's early heritage. The construction work of the new building along with the Chapel was completed in 1876. The final payment on the building was made, and the painted murals and decorations were completed by John La Farge in 1877. The main focus of Trinity Church is the central crossing tower, which is visible from all angles. The floor plan is in the form of a Greek cross. The massive central square tower, in part designed by Stanford White, was inspired by the Cathedral of Salamanca in Spain. The front of the church was designed by Richardson, based on Romanesque architecture. Both the porch addition and the side towers (above) were completed in the 1890s after his death. The apse, with buttresses ending in thin columns between the windows, and the Parish House, with an attached cloister and exterior staircase, are other features of the church. The most noteworthy aspect of the church is the stained glass windows with varying styles of artistry, craft, and interpretation. Trinity Church supports a wide range of vital programs that serve people in the city of Boston. Trinity also welcomes visitors by sharing the story of the church's past, present, and future. Both guided and self-guided tours are available.
