Foul things lurk in forgotten places.
The Ancient Waterway (むかしのすいろ, Mukashi no Suiro?, lit. Waterway of old times), also known as the Old Waterway and Baron Waterway, is a location in the games Final Fantasy IV and Final Fantasy IV: The After Years. It is the sewers of Baron, and connects the city to Baron Castle. The entrance is located at the western edge of the city of Baron, and is locked with the Key of Baron.
It contains many hidden passages that the party must discover to navigate their way. There is a Save point near the end of the Waterway.
To get inside Baron Castle following the attack upon it by a horde of monsters, Ceodore and the Hooded Man, the latter of which seemed to have knowledge of Baron's structure, traverse this passage. Ceodore obtained the key to the secret passage from Cid's daughter, who lives with Cid near the waterway's entrance.
By turning right then walking straight from the entrance, a secret room will be revealed at the end of the hidden passage. The room contains a treasure chest with 1000 gil.
- 1000 accumulated gil

The background music that plays inside the Ancient Waterway is Final Fantasy IV's "Dungeon" theme.
