It's commonly known that Google Maps blocks out certain institutions, it doesn't replace the image of one building with another. But whatever it takes to keep believing your conspiracy theories 
Lol so you were one of the kids that got sexually molested at this castle? No wonder you're so sensitive about it 
No I'm glad I wasn't because I know one and she's messed up for life. There have been openend several investigations, but each time they were closed down quickly because of involvement of persons of "state interest". Let's just say I was involved in one of those investigations due to my business relationship with somebody who is often named in the internet articles.
Facts are: The castle is located on the boarder of three countries and was built by the King of Belgium, a small artificial country where the headquarters of NATO and the EU are located. These countries normally have a very transparent liberal policy and possession of arms is strictly forbidden. Boobytraps are also forbidden (Amerois is surrounded by boobytraps in the woods). The castle seems a country within a country, with his own laws. It has no official function at all, but it's often visited by very influencial people (George Bush attended it several times). Never ever anybody has given an explanation about what's going on over there.
Another fact is that Belgium is considered as the archicenter of the Illuminati. Visit the Palace of Justice or the Universities: everywhere you see symbols of freemacony. Former secretary-general of the NATO Willy Claes is a self-proclaimed Illuminatus from Belgium.
Third fact: Belgium has been plagued by several severe scandals involving organized pedophily and abduction, torture and murder of children. Two men were (completely apart from each other) judged and emprisoned (life sentence, isolated from other prisoners) as "serial killers" after having admitted the abduction of several children. They claimed to have worked "on command", but nothing has ever been done in terms of investigation. Their action radius was exactly the neighbourhood of Amerois. One of them escaped during a transport (in very strange circumstances) and was found back (by a civilian!) hiding in the woods next to... Amerois.
I'm not into the satanic and reptilian theories. The only thing I know for sure is that in that particular place, very influencial people from all over the world are gathering on specific moments and that they are doing a hell of a job to cover it up. They just allow some obvious nutheads to spit nonsense about it, but serious inquieries you will never find.
