The Federal Street Church (established 1729) was a congregational Unitarian church in Boston, Massachusetts. Organized in 1727, the originally Presbyterian congregation changed in 1786 to "Congregationalism", then adopted the liberal theology of its fifth Senior Minister, William Ellery Channing, (1780–1842). For most of the 18th century the church was known as the Long Lane Meeting-House. In 1788, state leaders met in the relatively spacious building to determine Massachusetts' ratification of the United States Constitution. Thereafter the church renamed itself the Federal Street Church in honor of the event. In 1803, it called William Ellery Channing, (1780–1842), as its minister who defined "Unitarian Christianity" and launched the Unitarian movement, making the Federal Street Church one of the first to define itself as Unitarian.

Trans National Place, also known as 115 Winthrop Square, was a proposed supertall skyscraper in Boston, Massachusetts, US. Original designs were completed by architect Renzo Piano (with Boston firm Childs Bertman Tseckares Inc.) who later left the project in March 2007. Trans National Place was intended to stand as the tallest building in Boston, Massachusetts, and New England, surpassing the 60-story John Hancock Tower by 15 stories and at least 210 feet (64 meters) to become the tallest building in the city. The developer was local businessman Steve Belkin, who also owns an adjoining mid-rise building, which would have been torn down as part of the project. The tower was cancelled in 2008 amid a declining commercial real estate market and after the Federal Aviation Administration objected to the building's proposed height, deeming the structure a possible flight obstruction to the air traffic of nearby Logan International Airport. The project was superseded by the Winthrop Center, a proposed skyscraper for which a design was selected in 2016.
