Specifically the Forth Bridge. The photo was made to calm anxiety about bridges, as it was designed after the Tay Bridge Disaster. It's a marvel of engineering, and a national symbol of Scotland. And pictures really can't do it justice. It's 9 miles long:

Edit: it's 2.5 KM long, about 1.5 miles. It's 9 miles west of Edinburgh. I don't know why my brain did that, but thanks to the two redditors who corrected me.

A historical demonstration in 1887 showing the weight of the central span of a bridge being transmitted to the banks through diamond shaped supports. The central "weight" is Kaichi Watanabe, one of the first Japanese engineers who came to study in the UK. Sir John Fowler and Benjamin Baker of Imperial College, who designed the Firth of Forth bridge, provide the supports.

Some info about the photo.

I can't wrap my brain around this.
