Piazza Navona and the long shadow of Domitian’s stadium

Piazza Navona in Rom is a Baroque city square that still follows the outline of the Stadium of Domitian, an ancient Roman arena laid out in the first century AD. Its elongated plan carries the memory of the athletics track that once occupied this part of the Campus Martius, giving the modern piazza an unusually stretched shape among Rome’s urban spaces.
