St. Paul's School is an independent K-12 college-preparatory school in Brooklandville, Maryland (a suburb of Baltimore), located on a 64-acre (0.26 km²) rural campus in the Green Spring Valley Historic District, about ten miles (16 km) north of the city of Baltimore. St. Paul's was founded in 1849 at Old St. Paul's Parish in Baltimore City by Reverend William Edward Wyatt. Throughout its history, St. Paul's has moved its campus five times, finally residing at the current grounds in Brooklandville. The focal point building on the Brooklandville campus is Brooklandwood, a mansion built in 1793 by Charles Carroll, one of the signers of the Declaration of Independence.
