The Spring 2026 Weitzman Lecture Series offers perspective on some of the most pressing issues facing built environment professionals, cultural leaders, and policymakers today—from climate migration to threats to heritage sites around the world. Speakers will explore the lessons of pandemic-era experiments for public space, the dynamics of urban renewal in Portland following a municipal plan to combat displacement, and how an interest in salt lakes became a mission to save our water systems, among other topics. Free and open to the public. Registration is required for some events.
