Dholavira is a very old city from a long, long time ago. People used to live there, and it was in what is now India. But it was a really special city because of how they built it and what they did there.
The people who lived in Dholavira built their city out of really big stones. They stacked them up high to make walls and buildings. They even made a special place called a tank where they could collect water for when it didn't rain.
But they did more than just build things! They were really clever people who knew how to read and write. They even made their own special language on pieces of clay that we can still see today! They also had special symbols they used to tell stories and share ideas.
And even though the people of Dholavira lived a long, long time ago, they had things in their city that we still have today! They had special paths called roads that they walked on and places for people to shop and trade.
So Dholavira was a really important city in India a very long time ago where smart and clever people lived, built things out of big stones and even made their own language and writing!
