The same unstated ironies are ignored en masse when the megaliths are all-too signposted, as with Stonehenge, Newgrange and the like. Tourists are a mixed bunch. The majority are content with sightseeing - a brief look at the more spectacular bits, a photograph, some knickknack from the shop and a chance to use the loos. In-between are all manner of 'weirdos' and culturally orthodox visitors. The myriad ways in which we can approach the past is a mirror of our pluralistic culture.
Ethnology also opens our minds to potentially more profound mythological landscapes.
We will all continue to live in our familiar, everyday concepts of landscape. No changes are made. No charge is made.
