The Arcadius Business Center is a skyscraper in Downtown Los Santos. Its design is based on the Westin Bonaventure Hotel; however, the Arcadius Business Center is an office building whereas its real-life counterpart is a luxury hotel. Whereas the Westin Bonaventure has 4 outer towers, the Arcadius Business Center only has 3 outer towers, and the outer towers on the Arcadius Center are the same diameter as the central core while the real-life building's outer towers are smaller than the central core. Unlike its real-life counterpart, the Arcadius Center is one of Los Santos' tallest high rises.
