Start with the objects that turn a landscape of holes, slag and stone channels into a readable mining system
Visit this museum before Thorikos. Its mining and metallurgy displays explain how ore moved from rock to washing tables and furnaces, while inscriptions and sculpture put Lavrio within the civic and religious world of ancient Attica. The scale is manageable: a focused hour gives enough context to recognise features outside without exhausting the rest of the day.
The Ministry page publishes seasonal hours, admission and accessibility information, but also asks visitors to confirm changes. Tuesday is normally the closure day. Arrive at least forty minutes before last entry and ask about tactile material if useful. Do not assume every case label is available in English; downloaded background makes the industrial sequence easier to follow.
