Castle Rock, Maine. Castle Rock is a town located in the state of Maine. According to one map, the town is situated just south of the towns of Mexico and Rumford in central Oxford County.

Castle Rock was founded in 1874 when the eastern Douglas County border was redrawn to its present location. Castle Rock was chosen as the county seat because of its central location. One of the first homesteaders in the area near today's Castle Rock was Jeremiah Gould. He owned about 160 acres (0.65 km2) to the south of The (Castle) Rock.. At that time, the settlement consisted of just a few buildings for prospectors, workers, and cowboys. In 1874, Jeremiah Gould donated 120 acres (0.49 km2) to the new town that was also now home to the Douglas County government. For the beginning the six streets named Elbert, Jerry, Wilcox, Perry, Castle and Front were laid out to build the actual town of Castle Rock.
