Forth Bridge.

Carnegie reads that "SCOTS really rate the Holyrood Parliament - though they weren't too sure of it at first. A survey by whisky makers Grant's ranked Londoners' and Scots' impressions of the greatest Scottish innovations of the past 50 years. Scots rated the parliament first, followed by the Forth Road Bridge and Dolly the sheep ... But Londoners ranked the Forth Road Bridge top - and even found room for the deep fried Mars Bar in sixth place."

Carnegie is surprised how could Scots rate the Scottish Parliament building on a par (at 22%) with the Bridge? Carnegie demands a recount and thinks that the surveyors in this case have got it badly wrong.
