As the commercial hub of Brisbane since ancient times, the brown-yellow building at the Crossroads will certainly catch your eye, as it was AMP's headquarters in the 1940s, and one of the most modern office buildings in Australia and even the southern hemisphere. In 1942, MacArthur, who had fled from the Philippines, established his command on the eight floors of the building, where the US-Australian coalition, based in Brisbane, began another bloody and fierce battle with the Japanese on the islands of the South Pacific. Now MacArthur's command was transformed into the MacArthur Memorial, which is about the life of Brisbane and MacArthur himself in World War II.
