The Maria Pia Bridge Overlooking the Douro River

Spanning across the Douro River near Porto, Portugal, this historic iron bridge is an engineering marvel of its time built by Gustave Eiffel's company. It features a distinctive arched design that elegantly connects the city to Vila Nova de Gaia. Below, terracotta rooftops cluster tightly along the riverbanks while modern structures rise further out into the distance under a dynamic sky dotted with clouds.
