The Solaceon Ruins (Japanese: ズイの遺跡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 catches 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.
In the anime, the Solaceon Ruins appeared in Journey to the Unown!, in which they were visited by Ash, Dawn, Brock, and Kenny. In this canon, the ruins are a temple dedicated to Dialga and Palkia rather than a simple cave, and statues of the Legendary Pokémon can be found in front of the temple. There is also a stone tablet that reads "When every life meets another life, something will be born" — a direct translation of the Japanese version of this writing instead of the English version that is used in the games.
After arriving in the ruins, Ash and Kenny decided to have a battle, but it had to be interrupted when the stairs Dawn was sitting on began to lift, causing Piplup and Aipom to tumble down the steps and Dawn to jump off to save her Pokémon. Seeing that, Ash, Brock, and Kenny rushed to rescue Dawn and everyone ended up inside the ruins, where they encountered several Unown. The Symbol Pokémon living there guarded a gold-colored cube that was stolen by CommanderSaturn of Team Galactic.
Following the theft of the cube, Saturn ordered his Bronzor to use Confuse Ray on all the Unown, leaving them confused and making them attack Team Rocket, as well as Ash and his friends. The group's Pokémon began attacking the Unown as well in order to defend themselves and their Trainers. Their attacks managed to snap the Unown out of their confusion and the Unown eventually calmed down, allowing Ash and the others to safely leave the ruins.
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 Grumpy and Flaky, who led them into the ruins. The main trio helped the Unown free their friends who had been trapped.
