Observatory Circle is a street in Washington, D.C. It runs from Calvert Street to Massachusetts Avenue near 34th Street. Established in 1894,[1][2] the street follows an incomplete loop, forming an arc rather than a circle. Number One Observatory Circle is the official residence of the Vice President of the United States.

The inside of the arc formed by Observatory was blurred on Google Maps.[3]
