We give a complete description of the cohomology ring $$A^*(\overline{Z})$$A∗(Z¯) of a compactification of a linear subvariety $$Z$$Z of a torus in a smooth toric variety whose fan $$\Sigma $$Σ is supported on the tropicalization of $$Z$$Z. It turns out that cocycles on $$\overline{Z}$$Z¯ canonically correspond to Minkowski weights on $$\Sigma $$Σ and that the cup product is described by the intersection product on the tropical matroid variety $${{\mathrm{Trop}}}(Z)$$Trop(Z).
