The Solaceon Ruins (Japanese: ズイのいせき Zui Ruins) is the set of ruins where the player can find the Unown in Sinnoh. It is found nearby Solaceon Town. If the player captures an Unown, then shows it to a boy in Solaceon City, the Seal corresponding to its letter will become available. The Solaceon Ruins are also featured in Journey to the Unown!.
In the first room has no Pokémon in it and there is writing in the Unown alphabet that indicates which exits to take to get to the last room. The second room has only Unown of the "F" variety, the third, has "R" and so on, spelling out the word "friend". The dead-end rooms (reached by not following the Unown alphabet instructions) house the other twenty varieties of Unown. The last room holds four items (Nugget, Rare Candy, Mind Plate, Odd Incense) and an inscription written in Unown script. In Pokémon Platinum the Rare Candy is replaced by HM05 (Defog). The writing reads as follows:
- Friendship
- All lives touch other lives to create something anew and alive.
The Japanese version of this writing is the same featured in Top-Down Training! and in Journey to the Unown!.
The room above the rest of the ruins, only accessible after the Ruin Maniac has finished digging his way through from Route 214, has both "!" and "?" varieties. The inscription in there reads:
- ?!
