School Building and Opening Hours

A contemporary school building in the heart of a historical industrial area.

Just minutes from the main station, our school building offers a state-of-the-art learning environment in what used to be part of the Sulzer industrial park.
Our students learn in generous, bright, modern and friendly classrooms and working areas. Sporting facilities and a park are in walking distance from the school and offer plenty of room to relax, play or do physical exercise. Why don’t you drop by for a visit and see for yourself?

School Building

Our school building is centrally located in the Tössfeld district of Winterthur. The extensive facilities in the contemporary building have been equipped with modern infrastructure. In addition to spacious classrooms, we also have a range of special-purpose rooms such as an art studio, a well-stocked library, a music room, and a multipurpose hall where we hold our school assemblies.

An adventure playground on our rooftop invites children to climb, play balancing games or use the swing. In our street soccer park, the older students can often be found playing table tennis, soccer or other ball games.

In the immediate vicinity of the school building, there are two spacious and modern sports halls. 
SIS Winterthur is easily accessible by public transport.
