SIGNAL / SIGN OF THE TIME
Nothing has changed, just a move of power from kings to CEOs.
Castles and churches are the physical reminders of the status that kings and landlords had over their people. They are large buildings that radiate wealth and power.
This concept of castles has never gone away; Castles in the sense of a building to radiate your wealth and power are very much alive in our society today, increasingly so with the large role companies serve in society. Nothing has changed, just a move of power from kings to CEOs.
Offices reaching into the heavens like a gothic church, and headquarters as memorable as the Disney castle, if you look around you in a big city these offices are reminders that time may move ahead but concepts can remain the same for hundreds of years.
