Trinity Episcopal Cathedral, Pittsburgh

Trinity Cathedral serves as the main cathedral for the Episcopal Diocese of Pittsburgh. The current Gothic-style church, which is the third building to accommodate the congregation, was finished in 1872 on the location of an old hilltop cemetery. This spot, situated on a terrace overlooking the historic "point" where the Allegheny River and the Monongahela River meet to form the Ohio River, held significance for Native Americans as a burial site. Early settlers also utilized it as a cemetery, and the congregation erected its second church there in 1824.

Trinity Churchyard contains the oldest marked graves west of the Atlantic Seaboard, including those of Native American leaders, French, English, and American colonists. The initial Trinity Church was constructed two blocks to the west of this burial ground at the foot of the hill or terrace during the late 18th and early 19th centuries.

In 1824, Trinity relocated to its present location in the middle of the churchyard on the terrace, featuring what is considered the first Gothic-style structure in Western Pennsylvania. John Henry Hopkins oversaw the design and building of the cathedral, which included buttresses, a tower, pointed arches, and a vaulted ceiling. The new Trinity Cathedral was completed in 1872, standing as the tallest building in the city until the construction of the Allegheny County Courthouse in 1888.
