The community developed into a center for law and lawyers, second regionally only to Boston. Its prosperity would be expressed in fine architecture. Sixty-three buildings on Charlestown's Main Street are now listed on the National Register of Historic Places. They include the Gothic Revival South Parish Church erected by master-builder Stephen Hassam in 1842, St. Luke's Church designed by Richard Upjohn in 1863, and the Italianate Town Hall designed in 1872 by Edward Dow, New Hampshire's most prominent architect after the Civil War. Dow also designed Thompson Hall, the centerpiece of the University of New Hampshire.
