The Chain Bridge is officially named after István Széchenyi, who strongly supported its construction.[1] The Hungarian capital's first permanent bridge, the Chain Bridge, began carrying traffic in 1849.[2] When inaugurated, the 202-meter central span of the bridge ranked among the globe's longest.[2]

Geography and history
English engineer William Tierney Clark designed the bridge in 1839, following an initiative by Count István Széchenyi.[3] The bridge is a larger-scale version of Tierney Clark's earlier Marlow Bridge in England.[3] It was designed in sections and shipped from the United Kingdom to Hungary for final assembly.[3] Local supervision of construction was handled by Scottish engineer Adam Clark.[3]

The bridge was funded largely by Greek merchant Georgios Sinas, whose name appears on the Buda-side southwestern foundation.[4] Stone lions carved by a sculptor were installed at the abutments in 1852.[2] During World War II, retreating German forces blew up the bridge on 18 January 1945, leaving only the towers.[5] Following the 1848 Hungarian Revolution, the bridge was opened to the public in 1849.[2]

In 1914, the bridge's cast-iron components received upgrades and reinforcement.[5]
