Today the Arnold Arboretum welcomes visitors through a number of gates and less formal entrances located around the three mile perimeter of the landscape. They provide open access to the beauty of the grounds throughout the year, from dawn to dusk. The Archives of the Arnold Arboretum holds a collection of images of Frederick Law Olmsted’s earliest designs for the Arboretum’s road system and entrances. These early designs show how Olmsted’s thinking evolved into the landscape we enjoy today. Designing the Road System
Olmsted’s first sketches of the Arboretum grounds show a very different looking road system.
