Navigate to the Pujiang郊野 Park, and upon entering from Gate 1, you'll see the landmark castle. (Note: "郊野" is typically translated as "suburban" or "outskirts," but it seems the park's official name keeps the Chinese characters. Thus, I've preserved "郊野" in the translation. If you prefer a more fluid translation, you can replace "郊野" with "Suburban" or "Outskirts.")
