Bellwood

Bellwood is the hometown of the Tennyson family, where Ben, Gwen, and Grandpa Max live. Various members of the Plumbers also live in this town. The Plumber base that stores the Hands of Armageddon is also below this town. Their newspaper is The Bellwood Bugle. The main elementary school of the town is Madison Elementary School.

It is only seen a few times in the original series: in And Then There Were 10, Goodbye and Good Riddance, and Ben 10: Race Against Time. However, it seems to be one of the main locations in Ben 10: Alien Force. It may be in California, based on the first stop in And Then There Were 10(Yosemite) and how long it took to get there. As of Ben 10: Alien Swarm, this city was shown to have many factories and warehouses. Other locations include the headquarters of the Plumbers.

Madison Elementary School
It is the main school of the city and also the school that Ben and Gwen used to go to before they became teenagers.

Ben 10
Refering to Goodbye and Good Riddance, Gwen was a transfer student but as this is a "what if?" episode,this is not true. The school has been seen twice in the series.

Hardware Store(Plumber Headquarters)
This headquarters was entered through an elevator that can be activated. This headquarters was full of pipes and seemed to be a center for pipes. Under the city, it held the Hands of Armegeddon which when attacked could cause natural disasters.

Diner
In Ben 10: Race Against Time, Ben gets bullied by Cash and JT and two girls he tried to flirt with earlier in the movie resulting in Grey Matter causing complete chaos at a diner where Ms. Dalton works.
