The Bok Amphitheatre at the Camden Library in Camden, Maine is a remarkable outdoor structure in which the landscape architect Fletcher Steele (1885-1971) deftly combined classical architectural forms with a local setting in a manner that set a new direction in modern landscape architecture. The amphitheatre, which is positioned behind the Colonial Revival style library, is sited primarily to maximize the views through the adjacent Camden Harbor Park to the Camden waterfront. In order to accomplish this, Steele set the long axis of the U shaped park at an acute angle to the ridge of the library building. While the subject matter at hand, an amphitheater, is a structure steeped in classical precedents, including symmetry, rectilinearity, and formal composition, the manner in which Steele used the form to create a fully modern landscape was remarkable in 1929, and continues to be highly regarded today. The Bok Amphitheater is presently listed in the National Register of Historic Places as a contributing resource in the High Street Historic District. The recently approved additional documentation was offered in order to raise the level of significance for this resource to the national level of significance in recognition of the importance of the Bok Amphitheatre to modern landscape architecture.
