While I was playing the Middle Ages, I was going to use the Palace as a placehorder for a harbour. I switched a city to palace and it said to be done in 115 turns. I right clicked the palace, but it said the palace was only 100 shields.
As you can see, my city is getting 7 shields per turn with 3 lost to corruption.
