I know that the US and Canada are generally dwarfed in this category by Europe which has many, many huge iconic religious edifices. For this thread, I'm interested in seeing pics of the tallest religious halls of worship (church/temple/mosque/etc.) in your US, Canadian, Mexican, Central, or South American city. I'm not a religious person in an organized religion sort of way, but find the architecture and histories behind them to be quite fascinating. I grew up in a very Catholic city which has a disproportionately high number of impressive religious buildings for a city of its size, so that may have something to do with my interest. And please, let's try not to list every church in your city... how about the tallest only?
