Northumberland County Courthouse

Why it's listed
Sunbury's courthouse is a three-story brick building with a clock tower, a 1911 wing to the east, and a front facade of three arched doorways framed in stone and crowned by a stone balcony. Its brownstone corner quoins and Italianate second- and third-story windows mark it as a Romanesque public building. The county commissioners chose in 1865 to copy the Lycoming County Courthouse of 1861, designed by Philadelphia architect Samuel Sloan, and the Northumberland building is nearly identical to that structure, which was razed in 1969. The clock was installed in 1872, and the bell was presented to the citizens by Simon Cameron. Its solid masonry construction, from before steel framing became common, is regarded as increasingly rare. The building also served as the setting for the 1878 trial and conviction of Peter McManus during the Mollie Maguire violence, and for property boundary suits that helped stabilize the area.
Significance in brief: The nomination argues the courthouse is a fine example of 19th-century Romanesque architecture, with the massive solid masonry that was lost once steel girders came into use. It also holds political and legal significance as the courthouse where the trial and conviction of Mollie Maguire member Peter McManus took place in 1878, and where boundary-settling ejectment suits were heard.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
