Alte Burg is like a big, old house that was built a very long time ago in a place called Langenenslingen. It was probably built to keep people safe a long time ago when there were wars and fights happening a lot. Now, people don't live there anymore because it's too old and falling apart, but sometimes people visit it to learn about what life was like a long time ago. There might be pictures, things to touch, and people to talk to who know a lot about the Alte Burg and its history.
