Stark Tower, est. 2005 and named after owner Tony Stark, serves as headquarters to the Avengers.
Built over a period of four years, it stands tall as a gleaming beacon of modern architecture. The top three floors were to be Stark's new home, but when the New Avengers were founded, he gave it to the team as a gift, to be their home when they needed it, to be a meeting place and base of operations.
Just like the Avengers headquarters, Avengers Mansion, Stark Tower is suited with state-of-the-art technology and a very extravagant interior, including hanging portraits from former Avengers. The place where it stands now was the former site of The Sentry's Watchtower before he erased all the world's memory of him. When the Sentry recovered from his "mental virus", the Watchtower installed itself atop Stark Tower, convincing Tony Stark that it was fate that really brought them together.
When the team came together in this place, Edwin Jarvis the butler was welcomed back to his position as caretaker and continues to look after a new team of superheroes.
After the tower's destruction during World War Hulk, Tony rebuilt it using S.H.I.E.L.D. funds. Since Tony has been removed from power and S.H.I.E.L.D. has been replaced with Norman Osborn's H.A.M.M.E.R., Osborn has taken the tower, known as Avengers Tower, as his own. The Dark Avengers used it as their headquarters. After Osborn is removed from power, the tower returned to Stark and with Sentry's death the watch tower disappeared from the roof top only to be replaced by an Asgardian arch.
During the attack of the Serpent, Red Hulk battled one of Serpent's Worthy, Angrir, during the fight, Angrir destroys the Stark Tower. In the aftermath of the later battle against the Serpent, Stark proposed himself to rebuild the Tower. Time later, the Tower was rebuilt with a new design and opened to be once more Avengers' headquarters.
