Just 5 minutes away from the exceptionally beautiful historical downtown (Kanton Aargau), the ISRH is located in the authentic building of the former Hotel-Restaurant «Drei Könige (Three Kings)». The inviting and pleasant atmosphere has a positive effect on the well-being and the school performance of the children. 

Rheinfelden, founded in 1130, is the oldest Zähringer town of Switzerland which will be rewarded with the Wakkerpreis of the Schweizer Heimatschutz, is situated in the lovely Fricktal (Frick valley). It is very popular due to its unique landscape, its attractive leisure time, cultural offers, outstanding traffic location, tax benefits and attractive real estate market. Basel, the closest big city, is only 15 minutes away. 

The Fricktal (Frick valley) is the fastest growing economic area in the Northwestern region of Switzerland and attracts many local and foreign decision makers. 

Due to the ISRH's strong annual growth, the current premises will soon be too small to accomodate the school. It is planned to move into larger premises at Bahnhofstrasse 26 (former Coop-building) in summer 2020.
