Questions are now being raised after a fire has ravaged one of Copenhagen's oldest buildings. 

Its iconic spire collapsed during the fire, as emergency services and passerbys rushed to save priceless works of art inside and other valuables. 

The 17th century old Stock Exchange building was currently undergoing renovations. 

Europe Correspondent Gavin Grey told Mike Hosking the building was covered in plastic wrap and scaffolding. 

He says investigators are seeing if the efforts made to save the building are the very thing that caused its downfall.
