In a place whose history has long seemed obliterated a pioneering hotel has just brought back some of the past.
San Blas is a southerly spot on Tenerife, one of the Canary Islands, not a holiday destination best known for archaeology, environmentalism or tourism of the cultural type.
But in the past few weeks visitors to the Sentido's Reserva Ambiental have been walking out of their bedrooms into mysterious twisted ravines, volcanic shafts and caves where men and women prayed for rain, paddled for fish and pounded their corn meal, probably for 2000 years.
The Canaries have a classical history shrouded in more than the usual degree of mist.
Were they the original 'Islands of the Blessed' hymned by poets, the winterless home of the happy dead? Or was that some other set of Atlantic rocks?
Did Juba the Carthaginian visit, conquer or merely make some marks on the ocean map? It is not easy to say.
The modern history of the Canaries is misty too.
The fate of the local Guanche peoples when their stone-age ended in the fifteenth century, is not one that anyone else has much wanted to remember. As the Encyclopaedia Britannica (1911) puts it, 'The Guanches, who occupied the Canaries at the time of the Spanish invasion, no longer exist as a separate race, for the majority were exterminated and ther remainder intermarried with their conquerors'.
As to precisely whose fault that was, you can read on amid tales of squabbling Castilians and Normans and not be much the wiser.
There is no sign left either of the giant dogs - the canines that may or may not have given the place its name.
Civil war, famine and mass emigration was the rest of the miserable story - with a brief economic boom from the export of tomatoes.
The first British tourists to colonise the south of Tenerife in the package-holiday boom of the sixties were not much interested in history either. Any 'winterless home' four-and-a-half hours from Luton was fine.
If some of these visitors looked themselves very much like the 'happy dead' - zimmering from fish-and-chip shop to tea-bar - what did they care? The mugs were the ones who spent their Februaries back home in Manchester.
In the last decade Tenerife has tried to put behind it this piece of colonial history too.
But the replacement has been by golf courses - environmental horrors on an island where water has always been scarce - and chintzy five-star old Canarian resorts.
And there is still a long way to go even here: wonderful old fishing villages are to be found but you need to take care when finding them
The Sentido has its five stars too - and every facility of the sort that wins them.
But its burnt-umber rooms and tufa-grey paths are a rebuke to garish glare. It saves power and water rather than spreading it over greens.
The Sentido chimes more closely with the bobbing boats and fish restaurants of the local Los Abrigos port than with those other Locals, the Nineteenth Holes and the Coronation Street bars.
In past visits to San Blas for my own 'winterless sun', I had watched the Sentido grow - and heard about the reserve too, never quite knowing what it would be when it was complete.
And now it's ready - for the hawks and falcons overhead and for the first trickle of walkers on the ground.
There is an irrigation dam that recalls the tomato trade - and a threshing floor from more ancient times.
In the innermost part of the ravines there is a large round black rock, propped against a small one, spanning a snake-like trench, a miniature version of the dried river bed itself.
Maybe 2000 years ago, maybe five hundred years ago, it was carved from the volcanic earth and used for rituals that we no longer know.
None of this might be worth reporting from Italy or Greece or the Americas.
But in the land of the winterless sun it is a welcome sign of forgotten worlds returning to new minds
