A Roman morning and a park afternoon →
Begin at St Michael’s and keep the outdoor part flexible around the weather.
A heated Roman floor still in place / ST ALBANS
See a surviving mosaic and the heating system beneath it in a purpose-built shelter within Verulamium Park. It is a compact archaeological stop rather than a second full museum. Looking for the route warm air took beneath the floor gives children and adults a clear question to explore.

The shelter is indoors but the approach crosses the park and climbs to the building. Add it to a dry-weather Roman route rather than relying on it for a whole rainy afternoon.
