The museum preserves the West Range, built around AD300, which is the last and grandest of three buildings on the site. The foundations of two earlier North and South Ranges are now outlined in chalk outside. The South Range was erected around AD 100, not long after the Roman invasion of Britain in AD 43 and was followed by the completion of the grander North Range around AD 200.

Since its re-discovery the villa and surrounding land have been excavated many times. Using artefacts and archaeological reports, the museum will take you on a tour from prehistory up to the modern day.
