Im not sure of the whole back story of the Prague Castle. It is one of the most visited landmarks around Prague, partly because of the Castle and partly because of the St Vitus Cathedral, which is absolutely amazing. The interior is also pretty spectacular. I must admit though when I was there, there were so many tourists that it did feel Disneyland-esque. Regardless the beauty of the overall castle and the cathedral definitely make up for that feeling. Also, the castle has probably the best panoramic views at the look out before you head down the stairs on the far side of the castle towards the city. Definitely grab one of the sticks with the skewed fresh potato chips on it! There is a food cart at the bottom of the stairs, treat yourself!
