About Radnor
Radnor Township, often called simply Radnor, is a first class township with home rule status in Delaware County, Pennsylvania, United States.
Radnor Township is part of the famed Main Line of Philadelphia. As of the 2019 United States census, the township's population was 31875. Radnor Township is the largest municipality in Delaware County by land area and the fourth-largest by population, following Upper Darby Township, Haverford Township, and Chester.
Radnor Township is one of the oldest municipalities in Pennsylvania. Radnor Township was founded as a part of the Welsh tract. The original settlers were Welsh-speaking Quakers, led by John Roberts, in an attempt to establish a barony of Wales in Pennsylvania. In about 1681, a group of Welsh Quakers met with William Penn to secure a grant of land in which they could conduct their affairs in their own language. The parties agreed on a tract covering 40,000 acres (160 km2), to be constituted as a separate county whose people and government could conduct their affairs in Welsh. William Penn, an English Quaker, laid out the township in an elongated rectangle located parallel to the Schuylkill River, and the borders of the township have remained unchanged since its founding in 1682.
In 1717, the Welsh Friends built a meeting house on a trail made by the Susquehannock in Radnor Township. Radnor Township grew around the meeting house and remained the center of population of the township for 200 years. The new township was named Radnor after the county in Wales called Radnorshire. The influence of the Welsh, some of whom were forced by heavy taxation to sell their land, waned in the latter half of the 18th century. A hint of Radnor's beginnings remain in the names of streets and places evident throughout the community, such as the St. Davids neighborhood, named for Saint David, the patron saint of Wales.
There are a number of colleges and universities located in Radnor Township, the largest being Villanova University. The Valley Forge Military College is located in the neighborhood of Wayne and Eastern University is located in the neighborhood of St. Davids.
