Gold Plated Hinged Pendant Thingy...?

[Cool Hand Fluke]

My hunting partner Frank found this thing yesterday in a S.F. park, he did not want it so he gave it to me!
This gold plated pendant has a center section that swings open. The part that swings open can just about hold a quarter.
What is the purpose? What would you put inside?

Place for a photo? Maybe a type of locket.

Your locket is known as a secret memory locket. The center portion slides out to hide a photo, hair, flower pedals, or any type of memento. Is the scene on the front engraved? The scene looks like Santorini, Greece. Super neat find Breezie

Looks more like a "Mill on the stream" kinda building to me.

Could also be a Hidden Coin Necklace, could have hid two coins, in the recese of the bezel, popular during georgian times.

That building looks like an observatory.
I see no cross on the building to indicate a church.
