Baldwin’s Book Barn is a five-story antiquarian bookstore housed in a rustic dairy barn built in 1822 by Quakers Brinton and Sarah Darlington. In 1934, William and Lilla Baldwin established their used book and collectible business nearby and then moved to “The Barn” in 1946. The old milking house was converted into a residence for the Baldwin Family and the stone barn became the bookshop and, for some years, a country store museum. We are located deep in the heart of the enchanting and historical Brandywine Valley in Chester County, Pennsylvania. Baldwin’s is one of America’s truly distinctive bookstores. Step inside and you are transported to another time and place. Today, our store is stuffed to the rafters with a treasure trove of 300,000 used and rare books, manuscripts, maps as well as fine paintings, prints and estate antiques, and other valued collectibles.
