This question is about plain old Civ 4, not any of the expansions.
I was just wondering what it means for Obelisk to go obsolete with Calendar. Obsolete city improvements still generate culture, but generating culture is *all* an obelisk does. So what is lost when it becomes obsolete? Does Calendar just mean you can't build them anymore?
Similarly, what about Stonehenge? Does Calendar take away the complimentary Obelisk provided from Stonehenge, so the city with Stonehenge still gets culture from the wonder, but the other cities lose their 1 culture/turn?
