  We study a gravity model in 2+1 dimensions, arising from a generalized
Chern-Simons (CS) density we call a Higgs-Chern-Simons (HCS) density. This
generalizes the construction of gravitational systems resulting from
non-Abelian CS densities in all odd dimensions. The new HCS densities employed
here are arrived at by the usual one-step descent of new
Higgs--Chern-Pontryagin (HCP) densities, the latter resulting from the
dimensional reduction of Chern-Pontryagin (CP) densities in some even
dimension, such that in any given dimension (including even) there is an
infinite tower of such models. Here, we restrict our attention to the lowest
dimension, 2+1, and to the simplest such model resulting from the dimensional
reduction of the $3$-rd CP density. We construct a black hole (BH) solution in
closed form, generalizing the familiar BTZ BH. We also study the electrically
charged BH solution of the same model augmented with a Maxwell term, and
contrast this solution with the electrically charged BTZ BH, specifically
concering their respective thermodynamic properties.
