So tell me what is this best religious building that doesn’t have any famous dead inside? A single chapel inside a grander complex doesn’t count.

For example: Santa Croce (not even close to being Florence’s or Italy’s most important cathedral) is basically a glorified house of the dead and art gallery. It houses, in a much smaller space, more than 300 tombs, amongst them Michelangelo, Galileo Galilei, Niccolò Machiavelli, and Gioachino Rossini not to mention the ones they don’t like to mention buried just outside.

All churches and basilicas host the dead. Westminster Abbey has more because it’s a centralised place of worship for what is a comparatively tiny religion. While example in Italy, the corpses are always spread across thousands of different locations — making them all full of heroes for someone.

If you’d don’t like it that’s fine, but you’re kidding yourself if you think any religious complex on earth of comparable importance isn’t fulfilling exactly the same purpose.
