Yes, absolutely - Berlin is the canonical example. The site of the wall isn't paved over or hidden, it's a line of bricks that runs right through the city, with several museums and memorials along its length.
The site of the Fuhrerbunker is marked with a sign, despite now being a carpark.
The memorial to the murdered jews of Europe stands as a chilling, disorienting reminder.
There are brass plaques, the famous 'stumbling stones' in places where individual jews were persecuted, marking their names, dates of birth, death and eventual fate (if it was known).
In contrast, Russia's soviet history is often glossed over or lionized.
Any extreme position is therefore regarded with a high degree of skepticism. I think that's pretty healthy.
Many German friends I made, expressed the desire that they not - for example - see what happened in Germany, happen in the United States of America. A concern I, of course, share.

It could start by not actively preventing discussion about it.
"The administration of one district barred Vasilyev from speaking with descendants there..."
Confront in this sense mean to 'face up to' something. 'To accept having to deal with something unpleasant'. Barring investigation of something is failing to accept having to deal with it.
