I didn't really try for this combo, it just sort of happened without me thinking about it. Built a HS between a mountain and two tile natural wonder, so +5 faith. Chose the Work Ethic founding belief for my religion, so +5 production. Got Hildegard of Bingen as my first GS, so +5 science. Thought "well, that's pretty sweet," and I never play the 100% Holy Site policy card, but you better believe I'm playing it on this one!
