Castelli International School is exceptional in many ways. It provides a high-quality, well rounded international curriculum delivered by a dedicated, highly qualified, experienced and long-standing faculty. It is exceptional in terms of its small class sizes and the intimate sense of community that pervades the school. It is exceptional due to its idyllic location, nestled between olive groves and vineyards in the Castelli Romani hills, overlooking the city of Rome. Situated high above the city’s smog, our gratitude and respect for the environment and our relationship with it is something that is integrated into our learning each day.
