Boston Public Garden. The Public Garden, also known as Boston Public Garden, is a large park in the heart of Boston, Massachusetts, adjacent to Boston Common.
   It is a part of the Emerald Necklace system of parks, and is bounded by Charles Street and Boston Common to the east, Beacon Street and Beacon Hill to the north, Arlington Street and Back Bay to the west, and Boylston Street to the south. The Public Garden was the first public botanical garden in America.
   Boston's Back Bay, including the land the garden sits on, was mudflats until filling began in the early 1800s. The land of the Public Garden was the earliest filled, as the area that is now Charles Street had been used as a ropewalk since 1796.
   The town of Boston granted ropemakers use of the land on July 30, 1794, after a fire had destroyed the ropewalks in a more populated area of the city. As a condition of its use, the ropewalk's proprietors were required to build a seawall and fill in the land which is now Charles Street and the land immediately bordering it. Much of the landfill material came from Mount Vernon, formerly a hill in the Beacon Hill area of Boston.
   Initially, gravel and soil were brought from the hill to the landfill area by handcart. By 1804, a gravity railroad had been constructed to rapidly bring material from the top of the hill to the marsh; today, Mount Vernon no longer exists, having been completely removed to be use
