Not sure if this has been mentioned before, but it seems to take a pretty darn long time for some buildings to be constructed (8 turns for a 'roman shrine to <insert God/Goddesses' name here>)...

Could someone tell me the rationale behind this bit?

P.S: Been doing research for Roman building descrs... and the depth of the information I've been able to trawl up is nowhere near what is asked for by the EB team...

Guess this isnt as easy as I'd thought it was
