Spamming historic events can generate a lot of tourism.Notre Dame is cool. but i never ever managed to build it. Problem with it is that it is on the lower side of the tech tree and you need Guild and Universities ASAP...
How do you win Tourism without Wonders? Museums are not enough in my experience
In my last game I got Notre Dame before the AI . I usually get education and theology but then switch to the bottom of the tree until chemistry.
