The Huntington Library, Art Museum, and Botanical Gardens

The Library building was designed in 1920 by the Southern California architect Myron Hunt in the Mediterranean Revival style. Hunt's previous commissions for the Huntingtons included their residence. The building features iconic bronze entry doors decorated with Renaissance printers' marks, created by sculptors Ulysses Ricci, Angelo Zari, and Corrado Parducci, based on Henry Huntington's insistence on using these symbols rather than zodiac signs. The historic public-facing wing, known as the Library/Art Building (LAB), is currently undergoing a major $127 million modernization project to restore the exhibition halls and upgrade infrastructure while preserving the historic exterior. The project aims to reopen the Main Hall in spring 2029.

The Huntington's art collection features over 50,000 works from Europe, America, and Asia. Highlights include Thomas Gainsborough's 'Blue Boy' and Sir Joshua Reynolds' 'Pinkie', which are among the most famous British portraits in the world. The library houses rare treasures such as the Gutenberg Bible and the Ellesmere Chaucer. In 2012, the museum acquired its first major work by an African-American artist, a 22-foot-long carved redwood panel by sculptor Elizabeth Catlett. The institution also holds significant collections of 18th- and 19th-century British and French paintings, sculptures, and decorative arts. A notable loss occurred in 1985 when a fire in an elevator shaft destroyed a full-length portrait by Sir Joshua Reynolds depicting Mrs. Edwin Lascelles.

The Botanical Gardens span roughly 130 acres and feature sixteen themed gardens, including the Desert Garden, Rose Garden, and Camellia Collection, which is recognized as an International Camellia Garden of Excellence. A major highlight is Liu Fang Yuan (Garden of Flowing Fragrance), a classical Chinese garden modeled after scholar's retreats from the Suzhou area. Opened in 2008 with a final phase added in 2014, the garden features hand-carved stone bridges, wooden pavilions, and 850 tons of Tai Hu limestone rocks shipped from China. The gardens also include the Rose Hills Foundation Conservatory for Botanical Science, a Japanese Garden with a Zen Garden and bonsai courts, and a herbarium. The Desert Garden was featured on a U.S. postal stamp in 2020.

The Huntington is a leading center for research, hosting approximately 2,000 scholars annually who conduct work in history, literature, botanical science, and art history. It serves as a vital resource for the academic community, with researchers over 18 accessing reading rooms upon establishing a research need. The institution's endowment, exceeding $700 million, supports major conservation efforts, including the treatment of rare books, manuscripts, and paintings. The Huntington also plays a significant role in public education, serving thousands of students through programs and site visits. Its collections and gardens have been used as filming locations and have received national recognition, including the 2020 postal stamp honoring the Desert Garden.
