The United First Parish Church is a historic Unitarian Universalist church located in Quincy, Massachusetts. It is also known as the Church of the Presidents because both John Adams and his son John Quincy Adams, the second and sixth Presidents of the United States, were members of the church and are buried in a family crypt located beneath the church.

The church was originally built in 1639 and was known as the Meetinghouse of the First Parish in Quincy. It has been rebuilt several times over the years due to fires and other disasters, with the current building dating back to 1828.

The church and the Adams’ tomb were designed by Alexander Parris, a prominent Boston architect, in the Greek Revival style. It features a large, central dome with a cupola and a portico with six columns.

Inside the church, visitors can see the historic pulpit where both John Adams and John Quincy Adams once preached. The church also features stained glass windows, a pipe organ, and other historic furnishings and artifacts.

The United First Parish Church is open to visitors for guided tours and worship services. It is a popular destination for tourists interested in the history of the United States and the Adams family.
