Round Keep Castles were a type of castle during the medieval times. They were not built on a motte, unlike shell keeps. They were an adaptation of the square keep castles except they had round or polygonal walls. Medieval builders couldn't make the round keep castles as big as the square keep castles, so they were often cramped for space.

its a castle to protect attacks of gun powder
They didn't have any corners so an attacking army couldn't collapse the corners. The arch is a very strong structure, so it was harder to destroy with siege machines.
the advantages of concentric castles are they have round shape tower's. it is made of stone so it is not flammable and doesn't rot like wood.
Shell keep castles are round rather than boxed. A castle that forms a circle is a perfect example. There are many in England.
