Salk Institute: architecturally famous but research areas restricted

The Salk Institute for Biological Studies, designed by Louis Kahn, sits on a cliff above the ocean and is widely photographed for its central courtyard, but it is an operating research institute with most interior spaces restricted to staff and approved visitors. Public guided tours are offered on a limited schedule and require advance arrangements; unsupervised access to laboratories and many buildings is not permitted. The campus address is publicly listed and the courtyard is visible from certain public vantage points, but substantial portions remain off-limits.
