The Forth Railway Bridge under construction, seen from South Queensferry, Scotland, taken by an unknown photographer in 1887. Constructed over seven years by engineers Sir John Fowler (1817-1898) and Sir Benjamin Baker (1840-1907) and completed in 1890, it was the largest steel bridge of its time.

Thanks to a recent coat of extremely weather-resistant paint, the bridge is now free of painters and scaffolding for the first time since it was built.
