Here Comes the Sun

Stonehenge, England's mysterious prehistoric megalithic site, was set up so that the sun would shine directly through the stones on the summer solstice. Along with the spring equinox (when day and night are of roughly equal length), this change of seasons was considered a time of rebirth.

The US has its own - albeit accidental - Stonehenge: On May 31 and July 11, the sun sets exactly in alignment with the gridded streets of New York City, creating what's been dubbed "Manhattanhenge." For the last 15 minutes of daylight, the buildings along the east-west streets are gorgeously illuminated. Because the city is set 30 degrees east from the geographic north, Manhattanhenge doesn't occur on the spring equinox (which takes place in March), but there's no better way to celebrate the constant rebirth of this always-changing city.
