Research Triangle Park in North Carolina

Research Triangle Park (RTP) is the largest research park in the world, and it is located near Durham, Raleigh and Chapel Hill, in the Research Triangle region of North Carolina. A small part of the Park stretches into Wake County, but the majority of the land is in Durham County.

It is one of the most prominent high-tech research and development centers in the United States and has been compared to Silicon Valley. It was created in 1959 by nearby universities and enterprises. Karl Robbins bought the land where the park is now built. The Research Triangle along with the Cummings Research Park in Huntsville, Alabama, the two largest research parks in the country, have turned the "New South" into one of the scientific leaders of the United States.

The park is 7,000 acres (28 km²) situated in a pine forest with approximately 1,100 acres (4.5 km²) for development. As of the early 2000s, more than 100 R&D facilities exist at RTP with some 37,600 employees. The park is next to Interstate 40 and the Durham Freeway.

The park is home to the largest IBM operation in the world; the company has around 11,000 employees in RTP.
