In the paper, we establish Squash Rigidity Theorem - the dynamical spectralrigidity for piecewise analytic Bunimovich squash-type stadia. We alsoestablish Stadium Rigidity Theorem - the dynamical spectral rigidity forpiecewise analytic Bunimovich stadia whose flat boundaries are a priori fixed.In addition, for smooth Bunimovich squash-type stadia we compute the Lyapunovexponents along the maximal period two orbit, as well as the value of thePeierls' Barrier function from the maximal marked length spectrum associated tothe rotation number $\frac{2n}{4n+1}$.
