François Gustave Théophile Seyrig (19 February 1843 – 5 July 1923) was a German-born French engineer, best known for designing bridges.
On 6 October 1868, he founded Eiffel and Company with Gustave Eiffel. Seyrig contributed to the Eiffel and Company project to build the Maria Pia Bridge in Porto, Portugal, which was finished in 1877. Seyrig presented a paper on the bridge to the Société des Ingénieurs Civils in 1878.
Later he worked for the Belgian firm Société Willebroeck in Brussels, and won the competition to build the Dom Luís I Bridge (also in Porto), beating the Eiffel proposal. He began construction in 1881 and the bridge was finished in 1886.
Alexandre Gustave Eiffel was a French civil engineer. A graduate of École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit Viaduct. He is best known for the world-famous Eiffel Tower, designed by his company and built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York. After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields.
Porto, also known as Oporto, is the second largest city in Portugal, after Lisbon. It is the capital of the Porto District and one of the Iberian Peninsula's major urban areas. Porto city proper, which is the entire municipality of Porto, is small compared to its metropolitan area, with an estimated population of just 248,769 people in a municipality with only 41.42 km2 (16 sq mi). Porto's metropolitan area has around 1.8 million people (2023) in an area of 2,395 km2 (925 sq mi), making it the second-largest urban area in Portugal. It is recognized as a global city with a Gamma + rating from the Globalization and World Cities Research Network.
DomCarlos I, known as the Diplomat, the Martyr, and the Oceanographer, among many other names, was King of Portugal from 1889 until his assassination in 1908. He was the first Portuguese king to die a violent death since King Sebastian in 1578.
DomLuís I, known as the Popular was King of Portugal from 1861 to 1889. The second son of Queen Maria II and her consort, King Ferdinand, he acceded to the throne upon the death of his elder brother King Pedro V. He was a member of the ruling House of Braganza.
The year 1886 in architecture involved some significant architectural events and new buildings.
Maurice Koechlin was a Franco-Swiss structural engineer from the Koechlin family.
The Garabit viaduct is a railway arch bridge spanning the Truyère, near Ruynes-en-Margeride, Cantal, France, in the mountainous Massif Central region.
Infante Dom Afonso of Braganza, Duke of Porto was a Portuguese Infante of the House of Braganza, the son of King Luis I of Portugal and his wife, Maria Pia of Savoy. From 1908 to the abolition of the Portuguese monarchy in 1910 he was the Prince Royal of Portugal as heir presumptive to his nephew, King Manuel II.
Maria Pia Bridge is a railway bridge built in 1877 and attributed to Gustave Eiffel. It is situated between the Portuguese Northern municipalities of Porto and Vila Nova de Gaia.
The Dom Luís I Bridge, or Luís I Bridge, is a double-deck metal arch bridge that spans the river Douro between the cities of Porto and Vila Nova de Gaia in Portugal. At its construction, its 172 metres (564 ft) span was the longest of its type in the world. It can be confused with the nearby Maria Pia Bridge, a railway bridge that was built 9 years earlier, which is similar in aspect to the Luís I bridge.
Eiffel is part of the Eiffage group and the descendant of the engineering company Société des Établissements Eiffel founded by Gustave Eiffel, designer of the Eiffel Tower.
Edgar Cardoso was a noted Portuguese civil engineer and university professor. In Portugal, Edgar Cardoso was a pioneer of experimental analysis of structures and of high precision instruments developed to measure parameters affecting structural behavior on small models of his own works.
A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.
Émile Nouguier was a French civil engineer and architect. He is famous for co-designing the Eiffel Tower, built 1887–1889 for the 1889 Universal Exposition in Paris, France, the Garabit viaduct, the highest in the world at the time, near Ruynes-en-Margeride, Cantal, France, and the Faidherbe Bridge over the Sénégal River in Senegal.

The Campanhã Railway Station is a 19th-century railway station in the civil parish of Campanhã, in the municipality of Porto, district of Porto. Opened in 1877, it is connected to the Metro do Porto, and provides access to local commuter trains to Aveiro, Braga, Guimarães and Marco de Canaveses, Intercity and Alfa Pendular trains to Lisbon, inter-regional trains to Valença, and the historical train to Pocinho.
Vila Nova de Gaia is a tourist destination in northern Portugal, located opposite Porto on the South bank of Douro river. The cities connect through several bridges over Douro river. Vila Nova de Gaia is home to several notable attractions, such as the Port wine cellars, Dom Luís I Bridge, the Teleferico, Monastery of Serra do Pilar, Douro Estuary and 18 km long beaches.
The Infante Dom Henrique Bridge, commonly known as Infante Bridge, is a road bridge across the Douro River in Greater Porto, Portugal. The bridge is upriver from the Dom Luís I Bridge and downriver from the Maria Pia Bridge.
