“There could be no better day for the new College of Commissioners to begin our work than this anniversary. Starting today, we are the guardians of the Treaties, the custodians of the Lisbon spirit. I feel this responsibility. It is a responsibility towards our predecessors, our founding fathers and mothers, and all that they have achieved.” In her speech, she underlined: “This [the House of European history] shows the road that has led us here. It shows the treasure that we have inherited. A continent in peace. The liberation from tyranny. A single market with unprecedented economic opportunities.
