Pupin Hall, Physics laboratory building at Columbia University, Morningside Heights, United States
Pupin Hall is a Renaissance-style building at Columbia University containing large lecture halls, research laboratories, and physics facilities spread across multiple levels. The structure features interconnected spaces designed to support scientific work and teaching.
The building was constructed in the mid-1800s and became the center for physics research at the university. A landmark nuclear experiment took place here, marking a turning point in the history of science.
The rooftop observatory serves as a gathering place where students and neighborhood residents share a passion for stargazing and astronomy. People come here to look through telescopes and connect with the night sky above the city.
The main entrance is on the fifth floor and connects to neighboring campus buildings through underground tunnels. Visitors should be prepared for multiple levels and internal passages, as the building layout can feel complex at first.
The building played a direct role in groundbreaking nuclear energy research that reshaped both science and global politics. You can still stand in the actual laboratories where these world-changing discoveries happened.
