Introduction
Nestled within the University of Pennsylvania campus in Philadelphia, the Richards Medical Research Laboratories stand as a pioneering achievement in both architecture and scientific research. Designed by the eminent architect Louis Kahn and completed in 1960, this iconic building not only transformed laboratory design with its revolutionary separation of "served" and "servant" spaces but also set a new paradigm in modernist architecture. Its distinctive use of concrete, brick, and glass, along with a modular layout of interconnected towers, demonstrates Kahn’s vision for natural light, structural clarity, and flexible research environments.
Recognized as a National Historic Landmark since 2009, the Richards Medical Research Laboratories continue to function as an active research facility while welcoming visitors eager to explore its architectural and academic legacy. This comprehensive guide provides essential details on visiting hours, ticketing, accessibility, travel tips, architectural highlights, and the broader cultural significance of this Philadelphia historical site. Whether you are an architecture enthusiast, a student, or a traveler, the Richards Laboratories offer a unique window into the intersection of scientific progress and design innovation.

Historical Background and Architectural Highlights
Origins and Commissioning
The Richards Medical Research Laboratories were commissioned in the mid-1950s by the University of Pennsylvania to support the university’s expanding medical research programs. The renowned architect Louis Kahn was chosen for this ambitious project in 1957, marking a pivotal moment in the evolution of laboratory architecture.
Design and Construction
Completed in 1960 and named after Alfred Newton Richards—a prominent medical researcher and former chair of the Department of Pharmacology—the building represents Kahn’s breakthrough in separating laboratory spaces (“served”) from mechanical and support systems (“servant”). This clear functional distinction is expressed in the building’s modular design, with four interconnected seven-story towers constructed of exposed concrete and brick infill, maximizing both light and flexibility.
Architectural Significance
Kahn’s design for the Richards Laboratories is celebrated for its transparency of structure, abundant natural light, and the visibility of mechanical systems. The innovative arrangement set a new standard for laboratory and institutional buildings, influencing generations of architects and serving as a foundational case study in architectural education (Wikipedia; EAA).
The David Goddard Laboratories: Expansion and Context
Adjacent to the Richards Laboratories, the David Goddard Laboratories—completed in 1965 and also designed by Kahn—expand the scientific and architectural significance of the site. Together, these buildings form a cohesive research complex and further underscore Kahn’s vision of modular, light-filled, and functional spaces.
Recognition and Preservation
In 2009, the Richards and Goddard Laboratories were designated as National Historic Landmarks and are contributing properties to the University of Pennsylvania Campus Historic District (UPenn Facilities). Their preservation highlights the balance between honoring architectural heritage and adapting to contemporary research needs.
