Patron, Lord Mayor Frank Klingebiel, was one of the speakers at the ceremony, as was the chairman of the citizens' association, Joachim Sievers.

For almost two years, the association called for community donations for the graduation pavilion. Around 400 citizens responded to the call. More than 100,000 euros were raised. The commitment was enormous. According to the civic association, everything from a large donation (10,000 euros) from the Salzgitter Civic Foundation, individual donations from private individuals of several thousand euros to small amounts in euros was involved.

The work began with the renewal of the pipe system on the brine pipeline, a civil engineering measure that preceded the actual construction of the graduation pavilion. This created the important prerequisite for the subsequent wooden scaffolding with brushwood bundles. The pavilion could then be erected over the spring.

A graduation pavilion is a facility for salt extraction. It consists of a wooden frame filled with bundles of brushwood (mainly blackthorn); the salt content of the brine passing through is increased by the natural evaporation of the water. The operating principle is therefore similar to that of a salt works. The 25 percent natural thermal brine in Salzgitter, which bubbles up from a depth of 243 meters, is one of the strongest in Central Europe and was mentioned in documents as early as 1125.
