A corridor ran from the entryway into the heart of the mausoleum, where there was a chamber with three niches to hold the golden urns enshrining the ashes of the Imperial Family. Two pillars flanking the entrance were mounted with bronze plaques inscribed with the Res Gestae Divi Augusti, the document describing Augustus' accomplishments and victories. Surrounding the mausoleum was landscaped parkland akin to modern public parks, affording a place of retreat at the heart of Rome's heavily urbanized Campus Martius.
