What is the name of the castle in my backround? Tell me please:)

Hello friends,

This picture was taken a little while back and I cannot remember the name of the castle in the background. Maybe some of my followers will help me out since it appeared in my previous posts on several occasions. All I can tell you is that it is one of the most prominent landmarks in Prague. Some of you that know Prague little more might even be able to tell me from where was the picture taken. All right, let's have some fun:). Let me know in the comments below.
