I have been looking into this for days, but this plant is difficult to identify without its flower. I reached out to a botanist at Dartmouth, who suggests that it is either one of two species-- a nasturtium (Tropaeoleum sp.) or a geranium (pelargonium). The leaves are what are called peltate, meaning shield-like with the stem attached directly underneath.
On further research, specifically of peltate leaves, this plant looks more like Umbilicus rupestris, which is commonly found in southern Europe and grows in damp rock crevices!
