The Forth Bridge was one of the first major uses of steel, and a landmark in bridge design. Also in 1889, the wrought-iron Eiffel Tower was built by Gustave Eiffel and Maurice Koechlin, demonstrating the potential of construction using iron, despite the fact that steel construction was already being used elsewhere.
The previous bridge on the site, El Gezira Bridge, was a swing bridge built between 1869 and 1871 by Linant de Bellefonds with the participation of France's Five-Lilles Company. [ 3 ] The foundation stone for the present Qasr El Nil Bridge was laid by King Fuad I on February 4, 1931. [ 1 ]
Falicon pyramid. The Falicon pyramid is a monument located at a rural site near the town of Falicon, on the French Riviera, near Nice. [1]It is constructed above a karstic cave known as the "Cave of the Bats" (Occitan: Bauma des Ratapignata) and is one of the few pyramids in Europe.
The sides' angle relative to the base is 51.52 degrees, an angle similar to that of Ancient Egyptian pyramids. [5] The pyramid structure was engineered by Nicolet Chartrand Knoll Ltd. of Montreal (pyramid structure / design consultant) and Rice Francis Ritchie of Paris (pyramid structure / construction phase).

The Anji Bridge is the world's oldest open-spandrel stone segmental arch bridge built in 595–605 AD. The bridge is built with sandstone joined with dovetail, iron joints. Most of the (restored) Great Wall sections seen today were built with bricks, and cut stone blocks/slabs.
The construction of the Egyptian pyramids can be explained with well-established scientific facts, however there are some aspects that are even today considered controversial hypotheses. The construction techniques used seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. It is believed that ...

The construction of the bridge is a marvel of 19th century engineering, consisting of a 6 metres (20 ft) high single span steel arch. The design, by the architects Joseph Cassien-Bernard [ fr ] and Gaston Cousin , was constrained by the need to keep the bridge from obscuring the view of the Champs-Élysées or the Invalides .
