On Friday, April 23, 2010, Erika Friderichs, chairwoman of the Mainz Monument Network, and her colleagues campaigning for the preservation of the Electoral Palace were delighted to receive the first subsidy agreement check. In beautiful sunshine, the chairwoman of the local board of trustees of the German Foundation for Monument Protection presented the first subsidy agreement check in the amount of €500,000. Marianne Grosse, head of the department of culture, monuments, and redevelopment, accepted the check on behalf of the state capital of Mainz.

Numerous citizens had contributed with large and small donations, with €250,000 of the donation coming from the Mainz Monument Network alone. Numerous activities such as benefit concerts, building block sales campaigns, and lectures had contributed to this. Grosse, head of the Department of Building, spoke of "a wonderful project" and thanked the active members of the Monument Network for their support.

Numerous members of the Monument Network were present at the handover ceremony. Among them was Professor Dethard von Winterfeld, emeritus professor of art history. He emphasized the urgency of the renovation in order to preserve valuable historical buildings. At the same time, everyone was able to see the progress of the renovation work on site for themselves. Ten axes in the inner courtyard of the north wing are currently being worked on in the first construction phase.
