If a place is rubbled, it means it is covered in pieces of broken buildings or other things.
Rubbled places can make people think of disasters, like earthquakes or wars.
Examples:
The rubbled city was very sad.
The rubbled house was once very nice.
The rubbled street was hard to walk on.
I don't want to live in a rubbled place!
After the big storm, the whole town was rubbled.
