  Studies of quarkonium production in heavy-ion collisions can be used for
probing QGP properties. The suppression and regeneration of bound quarkonium
states is sensitive to the medium properties. Modifications of the quarkonium
polarization in Pb-Pb collisions with respect to pp collisions may give further
insight into the suppression and regeneration mechanisms in the QGP. Quarkonia
are also sensitive to the initial stages of heavy-ion collisions, and
measurements in photonuclear collisions may help constrain the nuclear
gluon-distribution at low Bjorken-$x$. In this work, recent quarkonium
measurements performed by ALICE in Pb-Pb collisions at
$\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV will be discussed. Preliminary measurements
of the inclusive J/$\psi$ $R_{\rm AA}$ measured at both forward and midrapidity
will be presented. The J/$\psi$ polarization measured for the first time in
Pb-Pb collisions, as well as preliminary measurements of the coherent J/$\psi$
photoproduction cross section, will be discussed.
