There are really only two Malls in the US.
The National Mall is located in the middle of Washington, DC and is about 2 miles long and 1/3 mile wide. The park was originally designed by Pierre L’Enfant in 1791 and amended in 1901 with the McMillan Commission’s plan. It has evolved over the years but stayed true to the vision George Washington had of creating a place for the nation to celebrate their heritage and observe their First Amendment rights.
The Mall has seen presidential inaugurations, civil rights demonstrations, Fourth of July concerts, and Memorial Day parades. There are 43 fields where local clubs play softball, soccer, rugby, field hockey, volleyball, and polo. More than 25 million people visit every year and there are over 3,000 events scheduled each year. Seventeen museums and nine major memorials can be found on the mall. Along with all the structures are the 2,000 American elms and 3,000 Japanese cherry trees. All these things are free to the public.
