Prague Castle and why you should always walk to school

I have been trying to walk to and from school every day, but it hasn't yet become part of my daily routine.  This is mostly because I wake up too late.  These shenanigans stop today.  I finally walked through the Prague Castle area a couple of times in the last few days and was completely blown away.  Tonight, on the way home we walked up a new route that goes right past the cathedral, which is an amazing Gothic cathedral that is lit up very nicely at night.
