No photograph can capture this extraordinary art space created by mural artist Isaiah Zagar down at the quiet end of South Street in Philadelphia's Center City—you have to see it to believe it. It's also not easy to describe: an alternate universe? A magical mosaic environment? A creative outsider's brilliant vision? A terrarium of otherworldly folk-art delights? Decide for yourself when you take a self-guided tour of this one-of-a-kind, ever-expanding project. The site includes an immersive outdoor-art installation crafted from found objects and handpainted tiles, as well as indoor galleries. The opening hours vary due to occasional public and private events; make sure to check the online calendar.
