Praça do Comércio is one of Europe's enchanting squares, revealing itself against the backdrop of the expansive Tagus estuary in the south. In the time before mass air travel, this square stood as Lisbon's welcoming gateway, embracing sea arrivals who could bask in its beauty from their ships. Monarchs and dignitaries would disembark here when visiting Portugal, further enriching the square's historical charm. Photo taken by Emma George-Archibald, designed by Ryan Carpenter.
