The Smithsonian Castle is easy to pick out on the National Mall ​ — the mile - long [1.5 km] green swath with the Capitol at one end and the Washington Monument at the other.
Smithsoni lossi leiab kergesti üles National Mall’i, pooleteistkilomeetrise promenaadi äärest, mis ühendab Kapitooliumi ja Washingtoni monumenti.
