Renowned local architects, professors, and historians explore the political, economic, and design trends that drove Philadelphia’s development.

This year, we gather for the 2026 Architectural Dinner in the historic Union Trust Building. Originally part of a tripartite composition designed by architect Willis G. Hale in 1888, the building underwent significant renovations—including a new facade and roof modifications—led by renowned architect Paul Philippe Cret. Today, while the exterior still boasts Classical Revival details, the interior operates as a vibrant setting for large events less than two blocks from Independence Hall.
