Our museums remain closed due to COVID-19. While LA County Public Health has entered Phase 3 of the Roadmap to Recovery, allowing for the reopening of museums on June 12, our museums are still slowly welcoming back staff and are in the process of planning for new health and safety protocols in our galleries and gardens. Therefore, we will not be reopening until later in the summer. Sign up here to be the first to know when we will safely re-open to the public and in the meantime, stay connected from home.
