Rose Tower (Japanese: ローズタワービルRose Tower Building) is a tower located in Wyndon in Galar, standing at almost a thousand feet tall.[1] Under Rose's ownership, Rose Tower is the headquarters of Macro Cosmos and its many subsidiary companies. It is built on a Power Spot.[2] After its ownership is turned over to Leon, Rose Tower is converted into the Battle Tower.
Rose Tower first appeared in Sword and Shield: The Darkest Day!, where Ash was invited there for a meal there with Rose. Rose offered to mentor Ash, but he refused the offer, preferring to grow stronger while traveling the world himself. After spending a night at the tower, Ash left it the next day to reunite with Goh.

Rose Tower first appeared in Assistant, where Oleana was seen starting a day of work there while Rose was away for the day.
In Moonlight, Leon visited Rose at the tower to receive John's letter from him.
In Rumble!! The Horrific Darkest Day, after learning of the Darkest Day that Rose was planning to unleash, Henry, Casey, Hop, Bede, Marnie, and most of the Galar LeagueGym Leaders entered Rose Tower to stop the chairman. Oleana challenged the Gym Leaders at the tower's lobby, while the others took the elevator to the top floor. Instead of Rose, however, all they found there was a giant screen, through which Rose spoke to them from Hammerlocke Stadium's Energy Plant. He had planned to wait until the Champion Cup would give him all of Galar's attention to start the Darkest Day, but due to the circumstances having changed, he announced he would start it immediately. As such, everyone then headed for Hammerlocke to stop Rose.
In Oh My!! The Disappearance of Henry, following Eternatus's disappearance, along with Henry, the Rusted Sword, and the Rusted Shield, Oleana gave Casey access to Macro Cosmos's supercomputer at Rose Tower so that she could figure out where they were now. Since she knew that the artifacts had been covered in Eternatus's poison, she used the National Pokédex database to search signs for a matching poison around the region, quickly figuring out that artifacts had wound up at the Isle of Armor and the Crown Tundra.
Rose Tower was introduced as a Stadium card in the Pokémon Trading Card Game during the English Sword & Shield Series (the Japanese Sword & Shield Era). It was first released in the Japanese Infinity Zone expansion and the English Darkness Ablaze expansion, with artwork by 5ban Graphics. It allows the players to draw cards until they have three in their hand once per turn.
↑Sword and Shield, Hop, Rose Tower, 1F: "Listen, <player>... Don't know if you knew this already, but I've heard Rose Tower was built on a Power Spot. Yeah, you know what I'm saying... When we get up to the roof and have a bit of space, we can Dynamax our Pokémon!"
