SHEFFIELD'S 1970s 'Wedding Cake' Register Office is finally crumbling after more than 30 years and 30,000 matrimonial ceremonies.
Demolition experts have started knocking down the landmark building to make way for the next phase of the 90m Heart of the City redevelopment programme.
A huge excavator smashed through the outer walls before a "muncher" digger was due to "nibble" its way through the inner sections of the cake building.
Site manager Jeff Troops, aged 52, from Dronfield, said: "I married my wife Lynn here 25 years ago and now I'm knocking it down.
"I went for a pint with my best man last night and we had a laugh about it.
"But I'm not sad to see the building go - it's just another job."
The ageing building will be replaced by St Paul's Place - which will boast three office blocks, 230 luxury apartments and a new Millennium Square.
Couples can now marry at a new 2million wedding suite opened in Sheffield's Georgian Grade 1 listed town hall this summer.
Demolition manager Harold Smith said the building would be gone by the end of today, adding: "It's an easy job - like eating away at slices of a cake."
Sheffield Council leader Jan Wilson said: "The Register Office has been a landmark in the city for over 30 years and represents many happy memories for the thousands of couples who married here.
"But, as the city transforms itself, it's time to look forward to the next exciting phase of the Heart of the City project, which I'm sure will be as admired as the Peace Gardens, Winter Garden and Millennium Galleries."
The Millennium Square will be located next to the Peace Gardens, with a striking sculpture by Northumbrian artist Colin Rose as the focal point.
