Stanford Research Park stands on land on Palo Alto, California in the U.S. that is owned by Stanford University. Built in 1951, it claims to be the world's first technology-focused office park. It covers 700 acres (2.8 km²). The park's 162 buildings hold 23,000 employees who work for 140 different companies.
The area surrounds Page Mill Road , to the west of El Camino Real. Many consider this development to be the foundation of Silicon Valley.
