The 4 square-block museum displays traditional and contemporary art, natural history, and cultural history, although locals once referred to it as “the bunker” because of its low profile and many disjointed sections. The $62.2 million renovation by Architect Mark Cavagnero aims to change that by bringing in much more daylight and opening up the maze-like galleries. The renovation will allow the galleries to host extensive showings and will create a state-of-the-art archives for the more than 2 million objects in storage. The most obvious change is a new covered entrance and unified lobby. The isolated spaces are brought closer into circulation, encouraging visitors to mingle in Dan Kiley’s extensive gardens, the galleries and the patios.
