She is buried in the Royal Pantheon of the House of Braganza.

The altitude of the central part of Rome ranges from above sea level (at the base of the Pantheon) to above sea level (the peak of Monte Mario).

Not that you know how long number 11 actually is, but you would be able to compare number 11 against the Pantheon with number 11 against the Baths of Caracalla, and so on and so forth. If you were interested.

Unfortunately for her, the anchor line gets tangled around the feet of some Boy Scouts who are visiting the Pantheon, and they are immediately yanked out and given an extraordinary but terrifying tour of some of the domes of Rome, which would, from their point of view, naturally be hanging upside down.

And then I thought, that's too complicated. No, I'll just take my favorite bits and pieces and I'll put them inside the Pantheon but keep the scale, so you can see the top of Sant'Ivo and the Pyramid of Cestius and the Tempietto of Bramante all side by side in this amazing space.
