Today I got to explore the grounds of an old castle. We walked up a long road, then passed through a gate into a round yard with a wall around it. We climbed up some narrow steps and were able to look out through narrow windows where the archers used to stand. Furthers up the road, we came to the castle area and were able to watch the changing of the guard. They marched in formation, passed their rifles back and forth, and then the new guards took their positions in the gate houses. They have to stand perfectly still there for hours! Then we climbed up one of the turrets to look out over Budapest. We also got to watch a 3D movie about the history of Hungary down in the lower floors of the castle. My feet hurt from all of the walking, but I had a lot of fun exploring.
