I was born in Bristol and he was a large part of the city's heritage and featured in the school curriculum. I have an early memory of standing on the edge of the Avon watching the SS Great Britain come under the suspension bridge into the Cumberland Basin in around 1970.
Funnily enough, I visited the ship again just the other weekend for the first time in about 30 years. It is only apparent to me now just how advanced the ship was at the time. This was the very first iron-only ocean-going liner and even the use of a propeller was bleeding-edge when it was built, and yet some the techniques used were similar to what you might see now. If you're ever in the area, I really recommend a visit.
Also worth mentioning is Maidenhead Railway Bridge https://en.wikipedia.org/wiki/Maidenhead_Railway_Bridge
built in 1838, which held the record for the longest flattest brick arches in the world up until only quite recently I believe. It appears in Turner's famous painting "Rain, Steam, Speed" https://en.wikipedia.org/wiki/File:Rain_Steam_and_Speed_the_...
and also has a fantastic sounding echo underneath.
