My first choice would be our beautiful parish church. But as a pipelines engineer, I would choose one of Sir Joseph Bazalgette's sewers in London. I imagine holding the ceremony in one of the large weir chambers, with the rhythmical beep of the gas monitors in the background.
The guests would have to wear all the appropriate safety gear, and I can just picture my aunts being lowered down the manhole on a Didsbury hoist. Our vicar, who is an ex-mechanical engineer, would be in his element, examining the penstocks, and the sewers would give the most wonderful acoustics for the hymns.

Having married very recently and thoroughly enjoyed the occasion, I'd do exactly the same again. The Registry Office registrar and hotel catering manager were both wonderful and unpretentious people, intent on giving us a great time without any unnecessary frills or social conventions. It worked splendidly, and the sun shone too!

On the Iron Bridge in Ironbridge Peter Wadsworth, 57 director, West Sussex The British Airways London Eye. One pod would hold just the right number of guests and one revolution would be more than enough time for the ceremony and some sightseeing too.

Gill and I married in Cornwall in 1986 and I wouldn't change a thing. The wedding was in the local Methodist chapel where her dad used to preach. He was a farmer, so the wedding had to be after the harvest and our reception was in a converted barn. The weather was superb and the views from the farm were breathtakingly beautiful with the sea glinting in the distance.

'On cloud nine' - now there's a civil engineering challenge.

The service would be paced to allow the exchange of rings and kissing of the bride to occur at the top. Afterwards, a honeymoon on the Orient Express with the return trip on Concorde, just in time to catch the latest edition of NCE.

f I were to marry my wonderful wife again, I would choose St George's Chapel, Windsor Castle.
This wonderful building has everything: atmosphere, wonderful light, amazing proportions and a flat fan vaulted roof - an engineering act of faith.

Like the marriage itself, if you get the direction right, there is treasure to be found. If it goes wrong, you can put it on the backburner for a while to get rid of the heat. If the well is dry, then find an enormous amount of money to plug it and work for the rest of your life to pay for the mistake (so I am told).
