Atenistas are a team of active people volunteering on many different aspects of Athens society, helping people in need, getting Athenians to know their city, introducing unknown corners to the general public, exploring urban arts and traditions, repairing, cleaning and improving parks and squares, in general taking actions to make Athens a better place to live and introducing Athenians and visitors on a different perspective on all things "Athens".
One interesting action they recently took is to file all various monuments and statues you'll see scattered around the city and present their story.
They created a sheparate site here : http://www.athenssculptures.com/
It is still work in progress and most information is available in Greek, but if you have seen some statue that got you wondering, there are good chances you'll find it listed here. You may then use a translate site to get all the feedback you need.
