Love, wisdom, truth, and freedom are our DNA.
We are an international school with children from 5 continents and 25 countries. We are located at the foot of the Balkan Mountains in the picturesque village of Osoitsa — a small Bulgarian village that brings together the whole world.
Our children grow freely in a multilingual environment and in constant connection with nature. Love, wisdom, truth, and freedom are the DNA of our school. Through them, we nurture free-thinking, confident young people ready to conquer the world.

Mission and Values
FREE IN SPIRIT, CONFIDENT IN KNOWLEDGE
Our mission is to create and develop exceptional individuals — individuals who bring positive change and confidently forge their own path in the world: responsible, thoughtful, creative, and self-assured.
With unwavering dedication to courage, imagination, and creativity, we create an educational environment where children discover and develop their unique abilities and talents.
At our school, every child feels accepted, supported, and inspired to learn, explore, and discover the world. We combine academic excellence, creative freedom, and human values. We encourage natural curiosity about the world, as well as each child’s individual interests and talents, so they can unfold their full potential.
Openness, respect, and tolerance are core values of our international community of children from many cultures and nationalities. We value and respect every difference and foster a culture of mutual understanding. Our children grow prepared to thrive in a dynamic and interconnected world.
The Restoration
A New Life for a Century-Old School
Cosmos International School was established in 2022 with a clear vision – to create a school outside the city, in nature, while bringing new life to an old, abandoned 100-year-old school building in the village of Osoitsa.
The building is nearly a century old and was constructed from stone sourced from the nearby hill. It had been completely abandoned for 35 years. In just ten months in 2021, with great care and dedication, the school was fully restored.
The clock tower, built in 1927, is a cultural landmark designed by an Italian architect and constructed from hand-cut stone.
The school has three floors, each with four classrooms, as well as a principal’s office, medical room, libraries, and a theater hall.
