Street art immediately conjures images of large artworks that cover entire buildings; in Oltrarno, however, it takes on another form.
The works of Florentine artist Blub can be admired on water and gas service panels around the district: usually smaller and more subtle than classic murals, they can even go unnoticed if you're not looking out for them.
His works are colourful prints of famous Renaissance paintings, all with the same characteristic: his subjects wear a diving mask.
