Yesterday’s passing of the renowned Chinese-American architect sunk hearts across the world. This is, in part, because of the breadth of his creations—buildings that melded modernism, cubism, and a sensibility that was all his own. To celebrate his life and legacy, we’ve highlighted four of our favorites. (All quotes attributed to Pei himself.)

1. The Louvre Pyramid, France

“Architecture is the very mirror of life. You only have to cast your eyes on buildings to feel the presence of the past, the spirit of a place; they are the reflection of society.”

2. Suzhou Museum, China

“A lasting architecture has to have roots.”

3. The Rock and Roll Hall of Fame, United States

“Great artists need great clients.”

4. Museum of Islamic Art, Qatar

“Be the best, not necessarily the original.”
