Yeah. I think what happens is that the implied group of things in which the castle belongs changes. "The town has the castle" could be understood as “there is only one castle and the town has it” (the group is that of all castles). But it’s nonsense. Your understanding seems right to me, but I am not a native English speaker. It is something along the lines of “among the things the town has, the only notable one is the castle” (it’s the only castle in the set of things the town has).
What is tricky is that the group in which the castle is unique is implicit.
FWIW all that is barely different from German (I'm a German native speaker). These implied groups seem like a nightmare if you have to learn how they work. Since I "just know", I've never had to think about it much.
Native English speakers, please correct me if I'm wrong about the "the castle" example.
