Local claims to fame include several embassies, including the sprawling Embassy of Russia in Washington (with its legendary tunnels beneath) and the Visa Office of the Chinese embassy. Wisconsin Avenue in Glover Park is home to a variety of restaurants and other businesses. Guy Mason Park is between Wisconsin Avenue and the Naval Observatory just south of Calvert Street. It is the location of a softball diamond, a playground for small children, and an unofficial enclosed dog park. Guy Mason Park is also the location of the annual Glover Park Day festival, held in early June.
