An arts centre is a big building where people go to do all sorts of creative things. It's like a big playground for art and music!
Inside, you might find big rooms with lots of chairs and a stage where people can watch plays or concerts. There might be art galleries with lots of paintings and sculptures to look at.
Some arts centres also have classrooms where people can take art or music lessons. There might be big rooms with lots of instruments for people to play and practice on.
And the best part is, anyone can go to an arts centre! You can watch plays or concerts, look at beautiful art, or even take lessons to learn how to make your own art or music. It's a place where people can express themselves and share their creativity with others.
