Maria Pia Bridge

Maria Pia Bridge is a prominent steel arch bridge located in Porto, Portugal, spanning the Douro River and connecting the cities of Porto and Vila Nova de Gaia. The bridge was designed by renowned engineer Gustave Eiffel and constructed by Compagnie de Fives-Lille between 1875 and 1877. It was named after Queen Maria Pia of Savoy, the wife of King Luís I of Portugal, and was officially opened on November 4, 1877, in the presence of King Luís I of Portugal and other notable figures, including António da Silva Porto and Fontes Pereira de Melo. The bridge has been recognized as a significant example of 19th-century engineering and has been compared to other notable bridges, such as the Garabit viaduct and the Maria Pia Bridge's contemporary, the Brooklyn Bridge, designed by John Augustus Roebling.
