HistoryA character grade: shown, never part of Radnor Township’s overall grade.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Radnor Township’s 172 sits above most of its state (91% of Pennsylvania towns have fewer) while its 580 historic buildings outnumber those of 98% of U.S. towns.
NoteThe founding year comes from Wikipedia alone; no second source gives 1686.

The community of Radnor was founded in 1686 at the Radnor Friends Meetinghouse, which was located on Conestoga Road, a bypass of Lancaster Avenue connecting Devon and Bryn Mawr. During the Revolutionary War, the meetinghouse was used as an outpost for General George Washington's Continental Army. In 1872, the Pennsylvania Railroad's Main Line was constructed, which briefly passed through the southern section of Radnor. A station serving the town was established at King of Prussia Road, approximately one mile south of the Meetinghouse.
