Metameor?

 

"Metameor" was written on the slide, as best as I can judge...but that turns up zilch on Google.

The image - might shows the Ksar Ouled Soltane, a fortified granary located in southern Tunisia. 

Historical Purpose: Built by the Amazigh people in the 15th century, these structures served as fortified storage spaces called ghorfas for grain and dates. 

Pop Culture: It gained international fame as a filming location for the slave quarters of Mos Espa in Star Wars: The Phantom Menace. 

The slide's odd colour cast - unknown. Possible a slight light-leak.

The woman - You've guessed it, unknown. But she seems to be carrying a Swann Hellenic (WF & RK SWAN LTD LONDON) travel bag.

Bonus Fact - Ksar Ouled Soltane is located in the town of Soltane, which is south of Tataouine. Hmm, sounds familiar. 

Bonus - 

"The Wife's Mother is staying for the weekend...."

 

It's the rules. Any visit to an ancient Roman or Greek amphitheatre will always involve a middle-aged "wit" thinking he can launch into his pub comedy routine.

If only they could release the wild animals on him.

I think that this the Roman Theatre, Sufetula, Sbeitla, Kasserine Governorate, Tunisia

Bonus - Strange and wondrous creatures: plankton and the origins of life on Earth

Familiar, but Not What I Thought

 

So, there I was, preparing a random slide for posting, with no information on it, and thinking - "35% of all slides must be some impressive cathedral that the tourists had a coach trip to. Yawn."

...when I thought.... there's something about this location that doesn't look very church-y.

Sure enough, some search-fu revealed that this was Great Mosque of Kairouan.  Nice.

Bonus - Founded in 2014 with a goal to reintroduce oysters — a billion of them — into the New York Harbor by 2035, the Billion Oyster Project is about giving spent oyster shells a second life.
