  In this work, we constrain the Hubble constant parameter, $H_0$, using a
combination of the Pantheon sample and galaxy clusters (GC) measurements from
minimal cosmological assumptions. Assuming the validity of the cosmic distance
duality relation, an estimator is created for $H_0$ that only depends on simple
geometrical distances, which is evaluated from Pantheon and a GC angular
diameter distance sample afterward. The statistical and systematic errors in GC
measurements are summed in quadrature in our analysis. We find $H_0 = 67.22 \pm
6.07$ ${\rm km \ s^{-1} Mpc^{-1}}$ in $1\sigma$ confidence level (C.L.). This
measurement presents an error of around 9\%, showing that future and better GC
measurements can shed light on the current Hubble tension
