When you walk the High Line, with its lush gardens, sculptures, cafés, and sweeping views of Manhattan, it’s hard to believe it was once an abandoned elevated freight track. It’s all because the enthusiastic and highly committed residents who formed the Friends of the High Line were able to fight off developers who wanted to tear it down. Through a complex series of moves, including raising over $50 million and having most of the line removed from the national railway system, this beautiful “park in the sky” was built. Join some of the most well-versed docents of the High Line on Tuesday evenings to hear more about the story of the park’s history, design, and landscape. Tours are free but space is limited, so arrive 15 minutes early to secure a spot. (In case of rain, check in the afternoon to see if the tour is still on.) Meets at the 14th Street passage.

Tuesdays, 6:30 p.m. Starts: May 27. Continues through Sept. 1, 2014
