How long was the construction of the arc de triomphe halted after Napoleon's reign had ended?

The construction of the Arc stopped in 1814 and resumed in 1830 under king Louis-Philippe, so it was halted for 16 years.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
