Especially those which were removed forcibly, whether by military coup, war, or anything similar?
I'm not really talking about something like a museum or anything which is providing more of a historical context rather than a memorialization if that makes sense.
Furthermore, if there are, then what is the public sentiment for that in whatever country/nation state does still honor past regimes?
If this is the wrong place to ask this feel free to point me in the right direction.
Edit: Should say "Do any"
Oops
While this isn't limited to the U.K., just using that country as an example you will find many statues & such of nearly every prior ruler who's ruling family was removed from power.
You even have Oliver Cromwell, considered a regicidal dictator by many with a statue right outside of the House of Commons.
Right next door you have the eventually overthrown Plantagenet's Richard I statue facing the House of Lords entrance. The actually deposed Richard III has a public statue in Leicester.
Along with the monarchs, there's Roman statues (Bath for example),
Memorials & statues for the various failed Scottish uprisings (the very large Wallace Monument being the most prominent but far from the only one).
These are just a few of many examples.
In Central Europe there are still plenty of Soviet monuments and statues hanging around. For instance, here is the memorial to the Soviet army, which I visited in Svidnik, Slovakia.
