Great job. I appreciate the voice dubs. It makes it much easier to watch while working. Thanks.

Thank you, Italy, for trying to preserve history for the whole of the world. I haven't toured the Colosseum in over 30 years. Sounds like I need to return.

[@gregedmand9939]

Making these ancient monuments into functional spaces for modern events, is something that the builders would whole-heartedly approve of. As long as the historic structure is respected and maintained I'm all for this kind of treatment. It was because they fell out of active use, that they decayed in the first place.

[@johnnycomelately6341]

My wife and I spend a week in Rome, split before and after our 16 night cruise through the Med and Black Sea (It was our Honeymoon). We visited the Colosseum and were enthralled by it. I hope to vist Rome/Italy again someday soon and look forward to seeing what the restoration has yielded.

TLDR: Roman concrete is harder cuz it is crappier quality. now that I have ur attention, enjoy the lesson about concrete. While Roman concrete does solidify in water, that is not why it is stronger than modern concrete. Modern concrete also hardens in water (which is why it is recommended to pour when its humid out and why Las Vegas has sprinklers on their construction sites). concrete is a mixture of cement (think of it like glue) and aggregate and water. The common modern cement formula is called Portland cement because it gives of the same color as the rocks in Portland, UK. The romans found that adding Silica into their cement formula makes it to where the concrete doesn't need to dry to harden (like the previous concrete solutions known to humans) because of the chemical reaction it has with water. Once the water mixes with the ions of the aggregate materials and because of the Silica, instead of drying out like it used to require, it rather changes the entire bonding process (not too sure on how to exactly word it) to where the water add makes some chemical crystal and they interlock together and become hecking strong. Now the reason why Roman Concrete is considered superior is because the entire formula was not mixed as well as the current solution. Now that does seem like the opposite would happen, but instead what happens is that there were little blocks of undissolved Calcium Oxide imbedded throughout the hardened concrete and once there was a crack in the concrete and it rained, the calcium oxide would dissolve in the water and essentially reharden. thats why in some Roman ruins that are still up, you can see different colors in some of the concrete. So technically, Roman concrete is not stronger, but rather self-healing. enjoy ur lesson of useless fact of the day

The work needs to be done. If a company or private individual can make it happen and they get a sign outside saying they did so, great.

Billionaires ought not even be give the choice. They are rich BECAUSE of the society in which they live. They do not NEED that much money to live lavishly the rest of their lives. They should be fully expected to give back to the societies that enabled their success. Consider that the Roman government did not build the coliseum, nor the aqueducts. The patrician class, who benefited out of proportion from Roman society paid for the building of public works. They paid for the games these venues put on. When 1% of the population holds more than 60 percent of all the money, they can afford to pay for everything.
