Have you seen the movie Inception (2010)? Without giving too much away, it has layers within layers within layers. However, Bourton Model Village – visited when I was camping near Bourton on the Water in 2016 has had something similar for a long time:
Inception at Bourton Model Village
The model of the village has a model of the village which has a model of the village which has, well, at least a little picture of a model of the village.
Although the photo – just taken with the regular 18-55mm kit lens on my D40 – is a year and a half old, I have only just got round to posting it online, so I am going to count it for my 52photos project.
