- Authenticity can not be restored

It can be a difficult task to rebuild the Notre Dame cathedral, and some of the over 800 old church will never be like before.

It tells Arne Høi, the head of department at the Institute for Architecture and Culture at The Royal Danish Academy of fine arts, Schools of Architecture, Design and Conservation.

- You can rebuild a form, but you can never recreate the history and authenticity that has been.

- On a staircase up to the tower can the steps be worn soft after many centuries of use. A new staircase can be made of the same material and shape, but the wear can't recreate.

On the way is history and authenticity some of the allersværeste to deal with, when faced with a restoration, he says.

the Fire in the cathedral broke out Monday around the clock 18.50.

Although the extent of the damage is not yet known, so is the Notre Dame a complicated building, tells the head of department.

- One of the challenges is that the church has been to over many periods. Therefore, the way in which to build on, materials and so on well vary in different places in the church.

And so it was also through a major restoration in the mid-1800s by the architect Viollet-le-Duc. This gives the building yet another layer of complexity.

Therefore, waiting there now a comprehensive analysis before one can even go in time with the restoration.

- This period (around the reconstruction, red.) is fairly well documented, but still awaits a comprehensive exercise in building archaeology work.

- Here you see, among other things, on what materials and construction techniques that are used. When it is finished, you then decide what restaureringsholdning you will bring.

- Will you use the same håndværkstyper and materials as at the time, or will you perhaps go for a more modern way, he says.

in addition the flames can the many millions of gallons of water used in fires also do major damage to a building.

But it will in the coming days would uncover the extent of, says Arne Høi, however, believe that the damage will be irreparable.

- I have no knowledge to that of other large buildings has not been possible to reconstruct parts of the construction. So I think it's good, you can. But it will possibly require the redevelopment of the lost craft.
