Located in the northwest area of Washington, DC between Cleveland Park and Woodley Park, this is a 20-acre estate that is open to the public. The park is over 100 years old. It became a DC landmark in 1979 and was listed on the National Register of Historic Place. The Washington International School owns and occupies six acres in the northwest area of the park. From a short distant you can see the National Cathedral and hear the cathedral bells ringing.
