Calder Gardens, a new art and nature destination along Philadelphia's Benjamin Franklin Parkway, has opened. The venue features a gallery dedicated to the renowned sculptor Alexander Calder, as well as outdoor gardens designed for contemplation and reflection. Beneath the gardens, an indoor and outdoor sanctuary features 31 Calder works, including mobiles and stabiles, some of which are displayed in the United States for the first time. The project is a collaboration between the Barnes Foundation and the Calder Foundation, which provided the curatorial vision for the indoor gallery. Tickets for the indoor gallery are available for purchase, while the outdoor gardens are open to the public free of charge.
