Citadel Tower

The Citadel Tower was a massive angular tower located in the center of the Galactic Empire's Imperial Center of Military Research complex on the planet Scarif. It housed a datatape vault which contained the plans for multiple top-secret Imperial projects such as the structural plans for the planet-killing battle station known as the Death Star, the details of Project War-Mantle as well as the classified project known as Pax Aurora.

The Tower featured a command center on its top from where the site command monitored the entirety of the complex, as well as an executive landing bay reserved exclusively for Director Orson Krennic. It also had a colossal satellite dish situated at very top of the spire for off-world communication purposes and, if necessary, transmission of datatape schematics. The dish's size was necessary as the entire planet was encased in a deflector shield which prevented ordinary transmissions from passing through. To activate the dish, a complex procedure had to be performed; namely, the site-wide signal disruptor had to be turned off via a master switch located close to the landing bay sector, the dish had to be manually re-oriented via a control panel on its base and the data-tape whose contents would be broadcast had to be manually inserted to a slot. This lengthy procedure was in place to ensure that no droids would access the vault's sensitive contents; theft by organics was considered to be impossible.

In 1 BBY, the Citadel Tower was targeted by agents of the Alliance to Restore the Republic, specifically an infiltration team known as Rogue One, who were attempting to steal the Death Star plans. By the time the Rebel Alliance Navy arrived to support the team on the ground, the Battle of Scarif erupted in space above the planet as well as on the ground. One of the rebels, Sergeant Jyn Erso, was confronted atop the tower by Advanced Weapons Research Director Krennic, whilst attempting to transmit the plans to ships overhead. After a short exchange, she successfully managed to send them to the Alliance flagship Profundity. Immediately after this, the security complex was targeted for destruction by the Death Star itself, on the orders of Grand Moff Wilhuff Tarkin, in an attempt to prevent the theft of the plans. On a single-reactor ignition, the battle station's superlaser fired upon the tower, destroying the top of it which was in the direct path of the beam, with the remains being vaporized in the subsequent shockwave.

The Citadel Tower first appeared in 2016 Star Wars Anthology film Rogue One: A Star Wars Story. Its interior was filmed at Canary Wharf in London.
