What does this mean?

Cloister with prune in Santa Maria la Real monastery, Najera, La Rioja, Spain.​

There are several images under this heading here: https://www.alamy.com/cloister-with...ery-najera-la-rioja-spain-image425869403.html
I'm guessing that 'prune' has been translated from the Spanish, but what word in Spanish? The first image is of the cloister with a well (pozo) in the foreground. Can pozo mean prune?
Thanks.

Well, it does say that captions are provided by the contributors. Maybe you could compare all the photos under that heading to see what the common features are. Are you thinking of buying the photo, or are you just looking for puzzles?

I was just looking for pictures of the monastery of Santa María la Real.

I believe the prune is a mistranslation of palm tree.
The translator must have confused a palm tree with a plum tree.
The English plum tree is ciruelo in Spanish.
Ciruela is Spanish for the fruit, plum.
The English prune is ciruela pasa in Spanish.

BTW, I think your questions about the three Blancas at the monastery has been solved.

In Spanish " pruno" is another word for "ciruelo" but is only used for the red one.
