This Massilia was designed not only to last indefinitely (save for the periodic gifts to Rome), but to do so with 100 culture and prosperity. As a bonus, it also receives the most positive comments from the people walking its streets, and a minimum of complaints from the advisors.
The city supports a population of 13,497 (currently counted as 13,478), and is expected to have a final population count of 13,378, with a total of 119 ghosts.
The periodic sea trade problems were disabled, because the constant nagging messages were becoming annoying. The city neither buys nor sells anything from the trading ships, so it isn't affected in any way.
This city wouldn't have been possible without the use of designs by other people, including:
Brugle's 40 GI block - http://caesar3.heavengames.com/downloads/showfile.php?fileid=566
I reoriented the block and rearranged some buildings so that the market ladies no longer perform 180 turns in the middle of their walks. As a result, it now only needs three markets instead of four. While the modified block holds fewer than 40 GI in this particular city, it is perfectly capable of supporting up to 43 of them.
Cicero's bridge placement - http://caesar3.heavengames.com/downloads/showfile.php?fileid=1399
His Massilia could fit 12 farms on the western-most island instead of the more commonly seen 11. It never occured to me to use a second bridge.
Caesar Sam's palace block - http://caesar3.heavengames.com/cgi-bin/forums/display.cgi?action=st&fn=2&tn=7656
My Massilia can't accommodate 12 luxury palaces , but it nevertheless made use of his palace block, in a slightly modified form.
