You've seen pianos nestled in the flora at the San Francisco Botanical Garden, providing unassuming stages to any talented (or amateur) passerby. Now you can find them tucked away somewhere even more unusual: underneath the Golden Gate Bridge.

PianFrancisco, an organization that places pianos in unexpected locations throughout San Francisco, is partnering with the Parks Conservancy and the Golden Gate National Recreation Area to bring pianos to Fort Point this weekend.

Fort Point is the vantage point on the southern side of the Golden Gate Bridge, originally built to protect the San Francisco Bay from potential intruders. Now, it lives on as a breathtaking viewpoint for tourists to take selfies. You may also recognize it from the tragic scene in Alfred Hitchcock's 1958 thriller "Vertigo," in which Kim Novak's character jumps into the bay.

This weekend, Fort Point will host free pop-up performances at the pianos featuring renowned local classical pianists. National park rangers will also be present, telling stories about Fort Point's fascinating past. Basically, it's a history lesson, a concert, and a sightseeing opportunity all in one.

Check out the hidden pianos at Fort Point on Saturday and Sunday, Aug. 24-25, from 1:30 to 3:30 p.m. The pianos are also open to the public to play for the whole weekend, from Friday to Sunday, Aug. 23-25, 10 a.m. to 5 p.m.
