1724 Chester Courthouse
Why it's listed
Built in 1724 in Chester, Pennsylvania, this two and one-half story stone courthouse is among the earliest public buildings still standing in the United States. The Pennsylvania Assembly authorized 300 pounds for its construction in 1723. Its south and east street facades are dressed stone, with rubble stone on the north and west, and its walls are two feet thick. A bell cast in London was added in 1729 and replaced during a 1920 restoration, and a three-sided judge's bay with large multi-paned windows was added in 1744. The first-floor courtroom was divided by a low railing to separate the judge and bar from spectators. Upstairs jury rooms had fireplaces and were used as classrooms when court was not in session. The building later served as the Delaware County seat until 1851, and it is regarded as the most important historic building in the county.
Significance in brief: The nomination argues it is among the earliest public buildings still standing in the country and the most important historic building in Delaware County. Its form is closely related to early Philadelphia domestic architecture rather than the market-stall town halls of Philadelphia and Boston. It served as the county courthouse after Delaware County separated from Chester County in 1789 and was later restored.

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.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
