It was very very famous and people from all around the world came there to study and learn more. It had a lot of buildings and gardens and was home to thousands of students and teachers. They had many subjects to learn, like math, science, medicine, religion, and philosophy.
Nalanda was really important for many reasons. It was a place where people of different cultures, languages, and religions came together to learn and share their knowledge. Students would spend many years studying and exploring different fields with knowledgeable teachers. They also had a big library with lots of books from all over the world.
