Portugal, Lisbon... The commercial square is the trade square, where Portuguese people do business with the outside world. The square is very large. There are many flags on both sides. Not far away is the wharf where the ocean cruise ship stops. There are policemen at the Arc de Triomphe. Be careful when taking pictures. There are thieves! The square is so big that it has a beautiful view facing the sea. Pictures must be taken against thieves!!
