Casti Village

Thriving in the Moment 

With a long history of empowering young women and a bright future ahead on our modernized campus, we know that throughout construction, we need to prioritize the present, centering the students in our learning community today. With Phase 1, the underground garage, nearly complete, we are preparing for Phase 2 by building a temporary academic complex, Casti Village, guided by three key principles: 

• Maintaining our outstanding program 
• Focusing on the student experience 
• Celebrating student traditions 

Keeping our current students at the center of all we do, the design features two stories of bright and spacious classrooms connected by a by a network of covered wooden walkways. These new spaces will be ready by the start of the 2026-27 school year and will replace our current square footage, offering fully equipped science labs, art studios, a library, a maker space and robotics lab, and devoted community hubs for the Upper School and the Middle School.

Throughout Phase 2, the Gunn Administration Building will be repurposed to support our program with faculty offices. The Chapel Theater will continue to be our primary performance and assembly space, and the Fitness Center will continue to be used for classes, including dance and fitness, and will be open for weight training, athletic practices, and competitions.

During COVID, Castilleja was known far and wide for having provided an intentional, rich, and engaging program, which included new ways to celebrate important milestones and beloved rites of passage. This transition to Casti Village is being handled with the same creativity and care, with input from students to focus on their experience.
