Lisbon

Lisbon is also an enchanting city, filled with wonderful architecture and spectacular views. There are still remains and buildings left from many periods of Portugal's history, but the earthquake of 1755 flattened much of the city center along the riverside. From the ruins, the city's grandest square, the Paca do Comercio, emerged. At one time, people arriving or leaving by sea landed in this area. (Now,of course, the waterfront area itself has a number of obras in progress – you can see them along the river edge.)
