- This article is about the actual tower. For the book, see The Tower of Nero.
Nero's Tower is a skyscraper owned by Emperor Nero of Triumvirate Holdings. The original tower is named Torre delle Milizie and is located in Rome, Italy while the most recent tower is located in New York City.
The tower is described as heavily fortified.
The tower first appeared in a dream of Jason Grace. Reyna Ramírez-Arellano and Octavian met here with Rachel Elizabeth Dare and Grover Underwood. Despite Octavian's attempt to start a conflict, Reyna heard Grover and Rachel out for what they had to say. Rachel gave Reyna a note, which stated that Annabeth Chase and Percy Jackson were in Tartarus. Although Octavian thought this was a trick, it also stated that Reyna must be the one to deliver the Athena Parthenos. Rachel also revealed Reyna's full name, to show her faith in what Reyna would do. Reyna agreed to carry out what Annabeth had written, but reminded Rachel and Grover that their camp still declared war by attacking New Rome, hence she requested that they leave. As soon as Reyna left, however, Octavian told the rest of the Roman officers that the legion would be changing their plans.
Rachel Elizabeth Dare revealed that the building was actually owned by Triumvirate Holdings. Through a lot of hard work, she managed to take a picture of three men inside. Unknown to her at the time, they were actually the leaders of the company: Nero, Commodus, and Caligula.
When Apollo and Meg McCaffrey receive a prophecy from Tyson and Ella, they realize they must head to the tower in New York City. Apollo also learns that he must face the Beast, his old enemy Python, and free the last oracle.
- The original tower is located in Rome around where the Gardens of Maecenas once stood. However, according the The Hidden Oracle and more trustworthy accounts, Nero was in Antium outside of the empire.
