This Cedar of Lebanon (Cedrus libani) tree is part of the historic tree collection at Tyler Arboretum in Media, PA.  The tree is part of the Painter Tree Collection and planted some time between 1830 and 1873 by Jacob and Minshall Painter.  The fence was recently constructed around the base to prevent visitors from walking on the shallow root system of the tree, in hopes that minimal human interactions will increase the longevity of this plant specimen.
