Chanticleer Garden is an estate and botanical garden located at 786 Church Road, Wayne, Pennsylvania. It is "quite simply, one of the most delightful gardens in the world." It is open Wednesday through Sunday, April through October; an admission fee is charged. The gate is crested with carved stone roosters, or chanticleers in French. The house and grounds were listing on the National Register of Historic Places in 1984.
The estate was built by Christine Penrose and Adolph G. Rosengarten, Sr., who was the head of the Philadelphia pharmaceutical manufacturer Rosengarten & Sons, founded in 1822 to produce quinine, and which in 1927 became part of Merck & Co. 
Their son Adolph G. Rosengarten, Jr. established a foundation to ensure that Chanticleer would be developed as a public garden. He hired Christopher Woods, a native of Britain, to develop the garden. After Rosengarten's death, Woods became the founding Executive Director and began a radical revision of the garden. He tore down Mr.Rosengarten's own stone house on the grounds to create the "ruin." The 35-acre (140,000 m2)property, was opened to visitors in 1993. The garden contains lawns and large trees, the Asian woods, a pond garden, the ruin and gravel garden, teacup garden, tennis court garden, and woodland.
