About Us

An international school in the heart of Lisbon

Astoria International School is a private school that combines an innovative educational approach with a multicultural and caring environment. At our school, we value each child’s individual learning journey, promoting their self-esteem, confidence, curiosity and love for learning from the earliest years. 

We are recognised as a school with innovative teaching, with a strong focus on academic excellence, social-emotional skills and active learning. Our facilities, conveniently located in a central and peaceful area of the city, are designed to stimulate autonomy and student well-being. 

Educational Stages and Learning Pathway

From Nursery to Middle School, Astoria European School offers a continuous educational pathway aligned with the highest international standards. 

A Progressive Multilingual Approach

At our school, multilingual education follows a clear and intentional progression, designed to support long-term language development rather than early overload.

Our students begin with bilingual learning in English and Portuguese, progress to a trilingual model with the introduction of German, and later expand into a fully integrated multilingual approach that includes French.

This gradual pathway ensures linguistic confidence, academic continuity and strong preparation for international environments.

Our pedagogical mission and values

Our mission can be summed up in three words: “Preparing for Success”. That means we promote a careful child-centred education guided by key values: 

  • Resilience 
  • Sincerity 
  • Integrity 
  • Competence 
  • Responsibility


Guided by our motto (“Innovate, Create, Grow”), we aim for every student to discover their potential, inside and outside the classrooms.

Our teaching methodology

Inspired by the Modern School Movement and grounded in Howard Gardner’s theory of Multiple Intelligences, our school’s approach supports differentiated and personalised learning that care for each student’s pace, interests and abilities.

Our model is designed to encourage autonomy, engagement and good well-rounded development throughout the learning journey of children.

A space designed to learn and grow

Our facilities are an extension of our philosophy, combining functionality, comfort and care.

We have more than 600 m² of thoughtfully planned indoor space and 450 m² of safe and stimulating outdoor areas. Our school school offers flexible learning environments that include spacious classrooms, a library, a laboratory, an arts studio and dedicated sports areas.

Together, these spaces create a daily rhythm where focus and curiosity coexist with creativity, movement and moments of pause.
