Druelselstein was referred to as "the old country" by Reginald Fletcher, which generally indicates a European country like Hungary, Romania, or going further back, Transylvania. ("The Monster of Phineas-n-Ferbenstein".) In another episode, many people claim Doofenschmirtz had "some kind of a German accent", implying that if it was on a map, it would be close to Germany.
The people of Druelselstein live a very urban lifestyle. Children in Gimelschtump like to play games such as Kick the Schtumpel, and pastry delicacies include Doonkleberry Cake  and Doonkleberries. While most of the time, the people are happy (albeit except for Heinz Doofenshmirtz), poverty still exists. 
The people have a strong belief in black magic. As a tradition, lawn gnomes are placed in front of each house to ward it off. When lawn gnomes become repossessed, parents appear to do anything to make up for it, even making their children dress up as one. Their beliefs are so strong that Heinz had to let his best friend Balloony go because his father told him to stand still.
The people of Druelselstein speak a language similar to German; for instance, when young Doofenshmirtz is instructed not to move in a flash-back in "Lawn Gnome Beach Party of Terror", he was told, "Bewegen sich nicht", which is German for "Don't move!"
Otherwise, characters generally speak English, such as the Gunther Goatcheese's employee who tells the young Heinz to lock up after his party is over ("Raging Bully"), but that was probably not meant as if the populace spoke English, but is rather used for convenience's sake and because it has no direct comedic use as opposed to the former example.
