Buildings

My favourite is the pantheon, in Rome.
Not only because it's there to represent all the gods of the world, but because the building itself is a human skull. With a hole in it, at the top.
That's where the sunlight and the rain get in.

Interestingly it's lasted so long because it's made of unreinforced concrete.

If there's a documentary on the building of notable buildings, I've seen it. This may interest you. - :]

On top of what @Skittle-Head shared, Roman concrete as designed by Marcus Vitruvius Pollio (and supported by Emperor Augustus), was essentially a mixture of 1 part quicklime (calcium oxide) and 2-3 parts pozzolanic material (phillipsite from nearby volcanic ash, containing aluminates and silicates), along with aggregate and a very low mix water content. The result - a relatively low strength (by today's standards and structural requirements) but highly durable material (especially resistant to seawater due to the formation of calcium-aluminate-silicate hydrate gel). With structures like the Pantheon, the design was also quite sophisticated for the time in that the higher the structure, the lighter weight the mix designs used.

From buildings to walls to aqueducts to in their roads, the Roman Empire exceled at advancing construction engineering, and the use of concrete allowed them to expand their empire, agricultural output, industry and commercial trade, while providing sound structure for her citizens.

I like the mices' cantina behind the baseboard on Looney Tunes.

And the seismic region that it sits in as well!

I would like to see Petra in Jordan.

I have seen some neat places in France and Isreal but I really like some of the memorials and monuments in Washington DC. I enjoyed the artwork and acoustics in Capital Building. There are a lot of non-famous places that I have been to that are memorable but I don't think that I have a favorite. A job that I had many moons ago put me in a lot of rich folks' mansions---those were interesting.

Rome would be nice! I've always wanted to go but, you know; time & money, etc. Maybe one day.
India has some nice structures, that wouldn't be bad if I knew where to go & stay.
