Emperor Ishaq Corrino XV designed and built the Ishaq Hall of Magnificent Documents in Kaitain’s capital city of Corrinth. In its time the museum was "one of the most spectacular constructions in the burgeoning Imperial city." However, by the time of Shaddam Corrino IV it had been "swallowed by ever more impressive architecture" and "lost among the extravagant monuments on Kaitain." The museum was a repository for, among other things, the handwritten personal diaries of past Corrino Emperors.
