In 1825 the bell tower replaced one porch (the other is still intact), and side and transom windows were added to the front door.  Later in the 19th century the interior was altered to accommodate new uses: the lower boxpews were removed, and a floor inserted to create two stories.  Town meetings were held here for over two hundred years, until the space available became too small (1990s), but the building has always been, and is now, in daily use for town business.

The building is well-cared for, and for over a hundred years no major changes have been made in it.  A small book, A Sacred Deposit, available from the Washington Town Clerk, gives a complete history of the building.
 
 

The building and its sanctuary are of the traditional New England style, white inside and outside, simple and somewhat austere.  It is likely that the pews in the sanctuary were recreated from those taken out of the original Meetinghouse.   During the 1980s the building was raised and foundation walls and full basement inserted.  The Church has been in continuous use since 1840 and holds worship services -- welcoming all -- each Sunday morning.  (10:00 during summer months, otherwise 11:00.)   The Pastor of the Church is the Rev. William Salt.

For more than a hundred years this building served as the principal school house in Washington, and was known as the
Center School.  There had been an earlier school house near this site, a small brick structure, but by the 1880s it was both worn out and too small.  About ten years of intense controversy (size, style, cost, location) preceded the construction of this building in 1883.

Eventually, it was decided to build a new school in the general style of the other town buildings, and place its facade flush with the Church.  It proved to be a perfect solution, both for the needs of the school and the appearance of the town Common; and from that year forward it served as the Center School, and the whole Common has been the pride of the town.

It was the meeting house build in 1842 by a local group of farmers calling themselves Christian Brethren, who dissented sharply from the strict Congregationalism of the Church in Washington Center. Many of the Christian Brethren became Adventists about the time this building was first used, and thereafter some of them began worshiping on the Seventh Day; and eventually the majority did so.

In 1862 the Seventh-day Adventist denomination was born at this place and this was recognized as the first church.  The building is kept in good repair and is a regular point of pilgrimage.
