At first, the Botanical Building’s dome seems to belong with the surrounding monuments. Inside, the construction tells a different story. Thin strips of wood form a great open lattice above the planting beds. This is an airy horticultural structure, not a sealed glasshouse.
Forever Balboa Park traces the idea to plantsman Alfred D. Robinson, the design to Carleton Winslow and the building’s realization to architect Bertram Goodhue. Completed in 1914 and opened for the 1915 exposition, it was intended to demonstrate what San Diego’s climate could grow. The building and its collection were part of the city’s argument about itself.
The restoration is now part of that story. The City reopened the Botanical Building on December 6, 2024, after work that replaced redwood lath, reconstructed historic window arcades and improved access. Plants had been relocated during construction and returned afterward. The wooden lattice is both the building’s structure and its most memorable interior detail.
Look beyond the building’s front elevation, too. In an April 14, 2026 update, Forever Balboa Park reported the completion celebration for the Central Gardens and the reveal of the reconstructed pergola west of the building. The original pergola had been lost during World War II. Its five bays and redwood lattice restore another architectural frame for viewing the garden. The same update describes nine climate-conscious Mediterranean gardens and expanded accessible paths. The revived setting gives the dome a wider context: a building, a place to grow plants and a garden to move through.
Admission to the Botanical Building is free. The project’s visitor information lists daily hours of 10 a.m.–4 p.m., except City holidays. Make the interior an early commitment if it is a priority; an outdoor walk can continue after the building closes. The Lily Pond and the view back toward the dome deserve a separate pause from the interior visit.
