Campus Transformation

Expansion & renovation

The Portland Art Museum campus expansion and renovation project will completely transform the existing Museum and create a vital “cultural commons” in the heart of downtown Portland. Opening to the public in late 2025, the project adds 95,000 square feet of new or upgraded public and gallery space, provides increased access to our exhibitions and programs, offers new ways to experience the robust collection, and adds new amenities that address the needs of more diverse audiences.

This once-in-a-generation transformation affirms the Museum’s mission to foster spaces in which to connect with each other and art through experiences that broaden our perspectives. It also affirms that Downtown Portland and the cultural district on the South Park Blocks are vital to the strength of our city. Reflecting shared community values of transparency, accessibility, and inclusivity, the project will be a cornerstone in our city’s revitalization.

Transparency & access

The centerpiece of this campus transformation is the construction of the Mark Rothko Pavilion which provides a central and welcoming “front door” to the Museum, featuring a glass facade opening onto a new public plaza and seamlessly connecting the Museum’s two historic buildings. The Pavilion will be named in honor of renowned abstract artist Mark Rothko (1903–1970), who spent his childhood in Portland after his family immigrated from Latvia. Rothko attended Lincoln High School, took art classes at the Museum, and even had his first exhibition here at the Museum. 

When the project is complete, all people, regardless of their individual capabilities, will enjoy ease of access throughout the Museum’s spaces. Improvements to accessibility range from wider sidewalks, push-button doors, and easy-to-find ramps, to gender-neutral bathrooms and an open-air passageway that provides improved access to public transportation.

The Pavilion’s main floor will serve as an open public space, featuring seating and access to our café and store, while the upper floors of the Pavilion feature expansive new galleries, outdoor terraces, and spaces for sitting and rest.

New plazas on both the West and East sides offer central, accessible, and beautiful entry points to the Museum. The Jubitz Terrace on the second floor will offer elevated views of the South Park Blocks to the east, and the west-facing terrace on the fourth floor of the Pavilion overlooks the surrounding neighborhood on Southwest 10th Avenue. Additionally, the Museum café and store will be larger, offering a new modern shopping and dining experience.

New ways to engage with art

Upon completion in late 2025, visitors will encounter an entirely new Museum experience with completely reinstalled galleries; new, more intuitive pathways to encounter art; and more visibility for noteworthy collections such as Native American art. Expanded public and gallery spaces will allow the Museum to showcase more of its expansive collection, including new acquisitions by a roster of renowned regional and international artists.

We will also continue to expand and showcase media arts and storytelling throughout the Museum, especially in the Whitsell Auditorium and adjacent Blair Family Commons—the new destination for PAM CUT // Center for an Untold Tomorrow on the West side.

How to Visit

The Museum will remain open to visitors throughout the project. Some galleries will be inaccessible during various phases of construction. We are committed to reducing the environmental impact of construction (filtering air and reducing noise, for example), ensuring visitor and staff safety, and our visitor services associates are always here to help.
