The signing of the Treaty of Lisbon took place in Lisbon, Portugal, on 13 December 2007. The Government of Portugal, by virtue of holding Presidency of the Council of the European Union at the time, arranged a ceremony inside the 15th-century Jerónimos Monastery, the same place Portugal's treaty of accession to the European Union (EU) had been signed in 1985.^[1] Representatives from the 27 EU member states were present, and signed the Treaty as plenipotentiaries, marking the end of negotiations that began in 2001. In addition, for the first time an EU treaty was also signed by the presidents of the three main EU institutions. After the main ceremony, the heads of state and government took a ride on a decorated Lisbon tram together, symbolising the brotherhood of European countries on the path of European integration.
