The hook
Louis Kahn's most famous building is a bare travertine courtyard split by a single thin line of water that runs straight out to the Pacific.
01Why it's worth it
When Jonas Salk, fresh off beating polio, set out to build a research institute in La Jolla in 1960, he told his architect he wanted "a facility worthy of a visit by Picasso." Louis Kahn gave him this: two mirrored blocks of concrete and teak flanking a wide, empty plaza of travertine, and down the center of that plaza a narrow channel of water that pulls your eye out to the horizon and the ocean past it. There's almost nothing else to it, and that's the point. The emptiness, the light, and the one line of water make it one of the most quietly overwhelming spaces in modern architecture. Kahn mixed the concrete on Roman formulas to get its warm, pinkish cast. Architects make pilgrimages here. It's a working science institute rather than a museum, but they let visitors walk the courtyard on weekdays if you sign up ahead.
02How to experience it
It's in La Jolla near Torrey Pines, about eight hours from the Bay and a few minutes from the coast. Public visits run weekdays, roughly 9 to 4, with free pre-registration required, so book before you go. Come late in the afternoon, when the sun drops down the length of the water channel toward the sea. Pair it with Torrey Pines next door.
