I will start by presenting the wonderful compactification of a toric arrangement and some results on its cohomology ring. This first part is based on a paper from De Concini and Gaiffi. I will then focus on the toric arrangement of type An and give a combinatorial description of a monomial basis for the cohomology ring of its wonderful model. Such a description offers a geometrical point of view on the relation between some Eulerian statistics on the symmetric group. (This is a joint work with G. Gaiffi and O. Papini)
