Federal troops occupied the building late in the war. The school continued in operation as an elementary and high school for many years and later as an elementary school. The facility was closed in 1991. The narrow building was modeled after Independence Hall in Philadelphia and built on the site of a duck pond. A clock was added in 1837, and the building has since been known as the Town Clock.
Residents boast the clock is the longest continuously running clock in the United States.
The County Courthouse, across from the Town Clock, has watched Winnsboro's daily activities since 1823. Designed by South Carolina architect Robert Mills, the courthouse houses records dating as far back as the middle 1700s. Fairfield County has numerous churches, some of which have been in existence for over 200 years. Perhaps the most famous church, built in 1788, is the Old Brick Church, where the Synod of the Carolina for the Associate Reformed Presbyterian Church was organized in 1803. A note penciled on the wall of the Old Brick Church is testimony to a Union soldier's regret at the church's floor boards being taken up to build a crossing over the nearby river for General Sherman's troops.
