Not for the faint of heart, this famous museum of medical oddities is home to the remains of Einstein’s Brain. It’s located inside the headquarters of the College of Physicians of Philadelphia and also has other curious medical displays like the skeleton of the tallest man in North America. Unfortunately, Einstein’s brain is not on display as his family has only allowed the brain to be used for scientific study, but there are plenty of other odd and quirky things to behold.

These Magic Gardens are a folk art environment, gallery space, and nonprofit organization that showcases the work of mosaicist Isaiah Zagar. The artist and his wife devoted themselves to beautifying the South Street neighborhood when they moved to the area in the late 1960s. They helped spur the revitalization of the area by purchasing and renovating derelict buildings, often adding colorful mosaics. Zagar started working on the Magic Gardens in 1994 and spent the next fourteen years excavating tunnels and grottos, sculpting multi-layered walls, and tiling and grouting the 3,000 square foot space. Take a guided tour, attend a mosaic workshop, or come for the other public events like live concerts and dance performances.

Here’s something you’ll have to see to believe. These mysterious rocks actually ring musically when struck. The rock field occupies 7 acres of an otherwise wooded area, and is over 10 feet deep with boulders. Only about a third of the rocks ring, and it wasn’t until 1965 that a group of scientists discovered why. After performing numerous tests, they found that all the rocks do in fact ring, but some of them do so at tones lower than the human ear can perceive. However, no one knows exactly how the rocks ring. Scientists believe it may have to do with the freeze-thaw cycle that helped created the boulder field in the first place.

Hellam Township was a pleasant little backwater in a corner of York, Pennsylvania, founded in 1739. It boasts beautiful forestry, lakes, wildlife, and waterfalls, and yes, an alleged hellgate. The Seven Gates of Hell is, according to urban folklore, a series of portals in the Hellam Township which open an entrance to the fiery pit below. It is said that only the first “gate” is visible by daylight, and by night, the other gates become visible. Passing through all seven will take the visitor straight to hell, and it’s reported that nobody has passed five and returned to tell the tale.

Did you know that Philadelphia boasts one of the best traditional Japanese gardens in North America? Shofuso Japanese House and Garden actually stands on a portion of land adjacent to the first Japanese garden built in America which housed a 14th century Japanese Buddhist temple gate. The gate was devastatingly destroyed in a fire in 1955, but it did clear the way for a unique Japanese garden house looking for a home. Shofuso was part of a Museum of Modern Art exhibition called “House in the Garden.” This gift to the U.S. by the people of Japan to celebrate post-war relations stood in New York’s MoMa courtyard for two years before landing in Philadelphia.
