Any major city in North America that is more historical looking than Montreal?

I imply there could also be a number of historic buildings or two in another cities like Philadelphia, however thus far I’ve by no means seen one other metropolis in North America that has this stage of preservation for historic European type buildings, in an analogous scale and density as Montreal. I’m wondering why is that this? I’m certain Montreal isn’t the oldest European colony in North America, however how come there’s nothing prefer it all throughout the continent?
