Tuscan city whose main public space is the Piazza del Campo (5)

I believe the answer is:

siena

(Other definitions for siena that I've seen before include "Italian city strangely in sea" , "Tuscan town" , "Italian location" , "city in Italy" , "City of St Catherine in Tuscany" .)

I've seen this clue in The Times and The Sunday Times.
