Located in the area that is traditionally occupied by Adventureland, Frontierland at Disneyland Park opened with "Euro Disneyland" in 1992. Unlike all of the other instances, this instance has an elaborate backstory concerning the town of Thunder Mesa, founded by Henry Ravenswood to support the mining of Big Thunder Mountain. This backstory also serves as the foundation for several of the attractions, such as Phantom Manor, a version of the popular Haunted Mansion attraction that can be found at some of the other parks featuring a Western theme and a darker tone to fit in with the rest of Frontierland. The land is the largest of all of the Frontierlands thus far, containing the entire Rivers of the Far West within its borders.
