NIH Visitor Center, Nobel Laureate Exhibit Hall, and Tours


The National Institutes of Health is the nation’s medical research agency. NIH’s mission is to seek fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to enhance health, lengthen life, and reduce illness and disability. Learn more about the NIH and the research we conduct.

The NIH Visitor Center and Nobel Laureate Exhibit Hall on the NIH campus in Bethesda, Maryland, welcomes visitors from across the United States and around the world. NIH tour programs are designed for young adults, individuals, and small groups who are interested in learning more about how the NIH improves human health and prevents disease. The NIH Nobel Laureate exhibit honors NIH-supported intramural and extramural scientists who have won the Nobel Prize in chemistry, physiology, or medicine.
