About Medvode, our home town
Medvode is a town 12 km far from the centre of the capital Ljubljana, where there is the confluence of the river Sava and the Sora at the south – east edge of the Sorica field.
Medvode lies between the two rivers that’s why it got that name (Medvode – between water). It’s also surrounded by nice peaks and the Alps at the back.

The lessons are mainly in the mornings. School starts at 8.15 and finishes at 14.00. Pupils are included in many activities like: naturalistic (science), traffic, biological and computing clubs.
