As we travel down the country, Lisbon is Portugal's capital city!

Lisbon is the largest city in Portugal and let me tell you it is hilly!

Please see below sites/cities just south of Aveiro:

Lisbon: do yourself a favor and get a Lisboa Card and take the city by storm (it includes transportation fairs, skip the lines at museums, and museum entry/discounts), visit Torre de Belem → Mosteiro dos Jeronimos → Calouste Gulbenkian Museum → Museu Nacional do Azulejo → Padrao dos Descobrimentos

Castelo de S. Jorge → Miradouro da Senhora do Monte →

Praca do Comercio, and lastly end your end with a fresh pastel de nata at the best place to get it town Manteigaria.
