About Cascais

Learn more about the host city, Cascais.

Cascais is a beach town in Greater Lisbon, Estremadura, Portugal, at the end of the mouth of the River Tagus as it meets the ocean, with spectacular beaches to be found on its Atlantic shorelines. The combination of maritime leisurely charm, strategic position and location close to Lisbon made it a favourite residence of the Portuguese royal family and several other nobles and one of Portugal's first holiday resorts.
