  In ultrarelativistic nucleus-nucleus collisions, a deconfined state of
strongly interacting matter is thought to be produced, commonly known as the
quark--gluon plasma (QGP). Quarkonia, bound states of a heavy quark and
antiquark, are an important probe to study the properties of the QGP. At the
LHC, bottomonium (b$\rm\overline{b}$) is of particular interest to study the
QGP complementarily to the lighter charmonium (c$\rm\overline{c}$) system. In
addition to the measurements in nucleus-nucleus collisions, reference
measurements in proton-proton and proton-nucleus collisions have been also
carried out in order to better understand the bottom quark production and cold
nuclear matter effects. ALICE measures the bottomonium production in the dimuon
decay channel at forward rapidity ($2.5<y_{\rm {lab}}<4.0$) with the muon
spectrometer. In this contribution, the recent measurements of bottomonium
nuclear modification factors and azimuthal anisotropies in Pb--Pb collisions
are presented. The bottomonium production in p--Pb and pp collisions are also
discussed.
