The Old Observatory is situated at the following address:

Oude Sterrewacht
Sterrewachtlaan 11

You can reach the Sterrewachtlaan via the Kaiserstraat. In case you are going to the Old Observatory by car, we recommend parking your car at the Haagweg and completing the rest of the journey by foot. This is due to the poor parking possibilities in and around the Kaiserstraat. The car park at the Haagweg is opened 24 hours a day, can accommodate about a thousand cars and offers free transport to the city centre.
