Naples is in some ways like one big museum of living history with its many churches, museums and archaeological excavations. Far too much to see and do in just a couple of days, but relatively easy to get some sense of the scope of it by walking the streets and popping in and out of churches. The subterranean city remains of a Roman market beneath San Lorenzo Maggiore gives some idea of the literal depth of history of the city. We also visited the National Archaeological Museum, which was an excellent precursor to our visit to Herculaneum. I was stunned at the beauty and richness of the mosaics, frescoes and artefacts recovered from Pompeii and Herculaneum - past visits to English Roman Villa excavations paled into insignificance against these.
