Never one to rest on its laurels, the only way is up for Lisbon with billions of euros of improvements on the horizon. The capital is set to benefit from a brand-new airport in 2023 which will double capacity and the local infrastructure is undergoing an exciting transformation with new subway and train stations, a shared bicycle programme and more cycle paths. The host of the Web Summit, the largest technology conference in the world, Lisbon has also cemented its reputation as a major tech hub.
