Portland Art Museum to unveil $116m transformation with Mark Rothko at its heart

The Portland Art Museum (PAM) will unveil a $116 million expansion and renovation on November 20, the largest single-organization arts investment in Oregon history. The centerpiece is the new Mark Rothko Pavilion, a multi-story glass structure designed by Hennebery Eddy Architects and Vinci Hamp Architects, which bridges the museum's 1932 building with a former Masonic Temple. The project adds 100,000 square feet of renovated space, including new plazas with sculptures by Ugo Rondinone, Roy Lichtenstein, Anthony Caro, and Clement Meadmore. The Rothko family is lending major paintings from their private collection for display over two decades, with a promised gift at the end of that period, and made a six-figure donation to the museum's $146 million capital campaign.
