Aer Lingus Plane Image

Flights to Lisbon

Portugal’s capital Lisbon enjoys the warmest winters of any major European city. Its Gothic cathedrals, palaces, and museums will delight you, while its warm and vibrant people will welcome you with open arms. Book your flight to Lisbon with Aer Lingus and discover happiness on a bun when you try the bifana, the country’s iconic pork sandwich.

Historical Sites in Lisbon

Discover the Monastery of the Hieronymites and Tower of Belém, a UNESCO World Heritage site. Start at the monastery, also known as Mosteiro dos Jerónimos. See the tomb of Vasco da Gama, magnificent carvings depicting the life of St. Jerome, and a statue of Henry the Navigator. Head to the Tower of Belem to view the Moorish-style watchtowers, find the rhinoceros carving, and learn about the tower’s role in Lisbon’s historic defences.

Museums in Lisbon

Immerse yourself in Baroque art at Museu Nacional de Arte Antiga, also known as MNAA. Witness the vivid reds of the Saint Vincent Panels and discover works by Jorge Afonso and Francisco Henriques. Then visit the Carmo Archaeological Museum and learn about the royal Gothic tombs. Afterwards, check out the Sicilian opera marionettes at the Museu da Marioneta, where you can watch a puppet show or discover the art of puppet-making.

Nightlife in Lisbon

Spend an evening in bohemian Bairro Alto. Over grilled sardines, listen to live singers performing fado. As the evening wears on, follow the crowds up the hill to the clubs. Don’t forget to stop for a glass of sangria.

Transportation in Lisbon

Lisbon’s metro offers the quickest way to travel between destinations. Buses and trams provide services in most areas. In some neighbourhoods, you can ride the funicular or take the lift.
