We consider finite $2$-complexes
$X$ that arise as quotients of Fuchsian buildings by subgroups of the combinatorial automorphism group, which we assume act freely and cocompactly. We show that locally CAT(
$-1$) metrics on
$X$, which are piecewise hyperbolic and satisfy a natural non-singularity condition at vertices, are marked length spectrum rigid within certain classes of negatively curved, piecewise Riemannian metrics on
$X$. As a key step in our proof, we show that the marked length spectrum function for such metrics determines the volume of
$X$.
