In many ways Herculaneum is arguably a more interesting place to visit than Pompeii. Surrounded by volcanic
rock, its location gives you a far clearer idea of the magnitude of the volcanic eruption. While roofs in Pompei collapsed under the weight of falling ash, only a few centimetres of ash fell on Herculaneum, causing little damage.
Subsequently, there was a succession of six flows of boiling mud (a mixture of ash and gases) which then solidified. These gradually buried the city’s buildings from the bottom up, causing relatively little damage. The good state of preservation of the site is due to its rapid filling by these flows, which prevented the buildings from collapsing. The high temperature of the first flow carbonized wood in the buildings and extracted water from it.
Restoration work is ongoing, and while a lot of the timbers have been replaced, there is still much of the original timberwork present, albeit, badly charred. Finally, the volcanic rock, ortufo, that covered the site for 1700 years formed an airtight seal. As a consequence there are many well-preserved buildings, many with the upper stories still intact, and some excellent frescoes and mosaics on both walls and floors to be seen.
Additional Excavations Herculaneum Tips
Walking shoes, or those with low heels, are highly recommended. In addition, in warmer weather you may want to bring your own bottle of water. For those with much younger children I advise a backpack style carrier if your stroller is not heavy duty and up to the ancient Roman roads. Allow 2-3 hours to tour the site.
