A borough in Berks County, Pennsylvania, United States with a population of 5,273 at the 2010 census nestled amongst other suburbs outside of Reading. It is perhaps best known as the place where author John Updike lived until he was 13, and it is the basis for the town of Olinger that he wrote about in his fiction. Shillington began in 1860 as part of Cumru Township, when local landowner and borough namesake Samuel Shilling sold some of his lots for residences. The area had an inn, originally built in 1762, called the Three Mile House because it was 3 miles (5km) from Reading on the Lancaster Pike. The inn was a popular stop for farmers going to the city's markets, and later it sat near a horse racing track built by Aaron Einstein in 1868.
