Bright market stalls, galleries and artists' studios abound in the area around Campo San Barnaba, a lively, atmospheric square which is very popular with locals. An attractive addition to this colourful scene is the boat of a fruit and vegetable salesman that moors alongside the Rio di San Barnaba. Overlooking the square, San Barnaba church houses the "Macchine di Leonardo" exhibition which is dedicated to machines designed by Leonardo da Vinci.
