Baba Vida is a really old and special castle located in Vidin, a town in Bulgaria. It was built a long, long time ago - over 2000 years ago! That's older than your grandma and grandpa combined!
The castle is really big, it has walls all around it, and a big entrance gate that is made out of stone. Kids who visit Baba Vida can pretend they are knights or princesses and play make-believe games in the secret passages and towers.
Baba Vida is very important for Bulgaria because it played an important role in protecting the town from dangerous enemies. In fact, many people say that Baba Vida is like a big, strong shield that helped to keep the town safe.
Even though Baba Vida is so old, it is still standing strong and looking majestic. It's like a time machine that transports kids and grown-ups to a totally different era. It's a really cool place to visit and learn all about history!
