##### Abstract

We previously (Adv. Math. 327 (2018) 390–409) constructed some projective wonderful models for the complement of a toric arrangement in an $n$–dimensional algebraic torus $T\phantom{\rule{0.3em}{0ex}}$. In this paper we describe their integer cohomology rings by generators and relations.
