Higher Aarburg elevation and the 1754 survey plan

In Aarburg, there are two phenomena or sites that are important in the context of the Swiss national survey. The key element today is the control point group AG 471–476 of the national levelling network, which is spread out around the church and consists of a total of six points. These control points were established over 100 years ago and are still maintained today.
