Q:

CK2 Hospital questions

My demesne has several hospitals (about 6).  My primary county hospital is maxed out, but I want to move my capital to Constantinople (more central location in my empire). So 2 questions: Do hospitals stack benefits? And, do I always get the benefit of my "best" hospital, or only my capital's hospital?

A:
