Nowadays we can see some discussions whether to reconstruct the Castle or not. And my opinion is following: I don't think that we should reconstruct this building  because it will cost great sums of money. Without any doubt it will become a proud of our city but I've read that a lot of citizens are against of this offer because they are sure that if we reconstruct  this old Prussian Castle we will return an atmosphere of Prussian times. It's not bad but people will associate this Castle with Hitler's times. It's not a fiction. I have really seen this statement on the Kaliningrad web page.
As for money outlays I'm sure that we have a lot of problems with money to cope with. I think we should spend it on repairing hospitals, roads for instance because the majority of citizens is not satisfied with their conditions.
As for culture features as I already mentioned we'll return Prussian's atmosphere and I suppose that we shouldn't do it because our city is already steeped by the air of ancient times.
And the last thing I want to underline that it is only my opinion and I'm sure that not everybody will agree with me but let it be just my own point of view.
