Lisbon hosted the ''NATO summit'' (19–20 November 2010), a summit meeting that is regarded as a periodic opportunity for Heads of State and Heads of Government of NATO member states to evaluate and provide strategic direction for Alliance activities. The city hosts the Web Summit and is the head office for the Group of Seven Plus (G7+). In 2018 it hosted the Eurovision Song Contest for the first time as well as the Michelin Gala. On 11 July 2018, the Aga Khan officially chose the Henrique de Mendonça Palace, located on Rua Marquês de Fronteira, as the ''Divan'', or seat, of the global Nizari Muslim Imamate.
