  In this note, we revisit the 4-dimensional theory of massive gravity through
compactification of an extra dimension and geometric symmetry breaking. We
dimensionally reduce the 5-dimensional topological Chern-Simons gauge theory of
(anti) de Sitter group on an interval. We apply non-trivial boundary conditions
at the endpoints to break all of the gauge symmetries. We identify different
components of the gauge connection as invertible vierbein and spin-connection
to interpret it as a gravitational theory. The effective field theory in four
dimensions includes the dRGT potential terms and has a tower of Kaluza-Klein
states without massless graviton in the spectrum. The UV cut of the theory is
the Planck scale of the 5-dimensional gravity $l^{-1}$. If $\zeta$ is the scale
of symmetry breaking and $L$ is the length of the interval, then the masses of
the lightest graviton $m$ and the level $n$ (for $n<Ll^{-1}$) KK gravitons
$m_{\rm KK}^{(n)}$ are determined as $m=(\zeta L^{-1})^{\frac{1}{2}}\ll m_{\rm
KK}^{(n)}=nL^{-1}$. The 4-dimensional Planck mass is $m_{\rm Pl}\sim
(Ll^{-3})^{\frac{1}{2}}$ and we find the hierarchy $\zeta< m<
L^{-1}<l^{-1}<m_{\rm Pl}$.
