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 east of Solaceon Town. If the player captures an Unown, then shows it to a boy in the town, the Seal corresponding to its letter will become available.
This map is the same in Pokémon Diamond, Pearl and Platinum versions.
The first room has a plaque/inscription in the Unown alphabet that indicates which exits to take to get to the last room. It reads:

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 and an inscription written in Unown script. In Pokémon Platinum one of the items is HM05 (Defog). The writing reads as follows:
The room above the rest of the ruins, only accessible after the Ruin Maniac has finished digging the Maniac Tunnel through from Route 214 (which occurs after obtaining one of each alphabetic Unown), has both "!" and "?" varieties. The inscription in there reads:
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
The ruins are featured in Knowledge of the Unown I and Knowledge of the Unown II and are the main setting of the latter one. Diamond, Pearl and Platinum encountered two Unown, later named by Platinum as Mr Hasty and Mr Relaxed, who led them into the ruins. The main trio helped the Unown to free their friends who had been trapped before the events of these rounds.
