The Palazzo Reina was a palace located on the planet Grizmallt that was built during the reign of Queen Elsinoré den Tasia, which began by 3950 BBY and ended in approximately 3900 BBY. The Palazzo was adorned with the Royal Script of Grizmallt and contained a room called the Heroine Hall.
Between 21 BBY and 18 BBY, Queen Apailana of the planet Naboo made a state visit to Grizmallt during which she visited the Palazzo Reina, accompanied by Senator Jar Jar Binks. The Gungan senator was familiar with the Naboo writing system Futhark, a descendant from the Royal Script of Grizmallt, leading him to famously misinterpret the name of the Heroine Hall as "Hero in Hell." The incident was recorded in "The Written Word: A Brief Introduction to the Writing Systems of Galactic Basic" by Doctor Milanda Vorgan.
The Palazzo Reina was mentioned in "The Written Word," an in-universe article written by John Hazlett and published on Hyperspace, a subscription feature on StarWars.com, on March 5, 2010. Hazlett chose the name of the Palazzo in reference to a backstory created by author Jason Fry for the cancelled reference book The Essential Guide to Episode I, where Fry planned to establish that Queen Tasia had seeded several colonies throughout the galaxy that used Spanish influence in their naming conventions as an Easter egg. As such, Hazlett specified that the Palazzo Reina could be translated as "Queen's Palace."
