    Philadelphia's Magic Gardens makes up a folk art center, gallery space, and a nonprofit organization showcasing the works of mosaicist（镶嵌设计师）Isaiah Zagar.

Zagar devoted himself to beautifying the South Street neighborhood in the late 1960s, when he moved to the area with his wife Julia. The couple helped the area by purchasing and repairing some old buildings, often adding colorful mosaics on both their private and public walls. The first such project was Julia's still-busy folk art store, the Eyes Gallery at 402 South Street.

Zagar started working on the Magic Gardens in 1994 in the deserted parking lot near his studio. He spent the next fourteen years sculpting multi-layered walls and decorating the 3, 000 square foot space. The installation（装置艺术），primarily consisting of found objects and contributions from the community, finally covers half a city block with countless patterns and colors. It shows Zagar's many artistic influences, as well as the events and experiences of his life.

In 2002，the owner of the once-unused parking lot decided to sell the land in response to rising South Street property values. Unwilling to witness the destruction of Zagar's neighborhood art environment, the community rushed to support the artist. His creation, newly titled Philadelphia's Magic Gardens, turned into a nonprofit organization with the intention of preserving and promoting Zagar's works at the site of the Magic Gardens and throughout the South Street region.

The Magic Gardens is now a permanent art institution that is open to visitors throughout the year. Trained guides are available to lead tours of the Magic Gardens and Zagar's surrounding public wall paintings. In addition, it offers monthly mosaic workshops led by Zagar himself, and regularly hosts concerts, dance performances, and other public events.
