The Piazza Mercato in Naples Italy and the church of Santa Croce e Purgatorio (closed since the earthquake in 1980).
On a morning of warm rain I walked the seafront of Naples in search of Piazza Mercato, a place that used to be a nerve centre for the city.
For well over five centuries this piazza was where goods, power, and messages changed hands – it was the Facebook of its day.
