The 366 Building.
366 is a 216 m (708 ft) tall skyscraper located in east of Staunton Island, Liberty City, in the neighborhood of Torrington, which appears only in Grand Theft Auto III and Grand Theft Auto: Liberty City Stories.
Design
The building design is very similar to the 500 Fifth Avenue, as it is only 12 feet taller than its real life counterpart.
Description
366 is located in the financial center, south of the Staunton police station, west of Kenji's Casino, east of AMCo. Petroleum headquarters and north of another building (the building is located next to all these places, as to the location that is on the map). In Grand Theft Auto III, the side-mission "Casino Calamity" is triggered by entering a Toyz van located in an alleyway next to 366.
