what is the advantage of having a treasure chamber?

i was wondering what is the advantage in building a treasure chamber and what is the case with artifacts and how do you get them?

treasure chambers hold the plans for building the WW, which will show up in the end game. When the plans apear in the game, if you have a treasure chamber, you'll see locations in your treasure chamber.

But for now, treasure chambers have some use. If you have an extra spot in a village, put in a level 1 treasure chamber and just leave it there, at level 1. It will produce 10 CP/Day, which is a huge amount for a single building.

when you need the spot, tear it out.

thanks

i was just wondering that, did't think to look here

Sure I read somewhere that just having a level 1 treasure chamber also helps with your culture points (10 cp which isn't bad for a level 1 building) and hence settling new villages.
