Yup I do think that it is probably one of from this century and that first link is most likely the most accurate account.
Still why would they build an air field out of stone when they had concrete, of course I have seen air fields that have been built from prefabricated
slabs so that could be one plausible solution BUT these slabs are HUGE have a look at it on google earth.
And why would they build it so very, very long making it one of the longest runway's in the world, the longest if we include the slabbed area that
extends for perhaps another third the length of the commercial runway unless of course the surveyor made a mistake, was drunk or was absent and the
builders just did there best to complete it not realizing that they had gone completely over kill.
Now as you know Archaeology being your field crop mark's and ground shadow's can sometimes be enlightening.
But as you know the city is ancient, many generations have worked the land, built and demolished there home's and business there, so most everything
may be of explainable origin, still some areas appear to hint that these slab's may also be wider than the modern runway and there may be two strip's
side by side there one completely buried and not used.
There are however a number of potential candidate areas for other strip's.
If for example you go to 13 degrees, 21 minutes and 7 second's north and 16 degrees, 39 minutes and 49 second's west you will see a dark area that
may be another that stretches to 13 degrees, 21 minutes and 37 second's north and 16 degree's, 39 minutes and 31 second's west, this has the potential
to be at least one secondary strip either disused or perhaps even buried.
Even if it is not ancient and it just may be then it remains' a site of vast importance due to the important role it may once have played in world
changing affairs and so qualifies as an important 20th century archaeological site.
It even appears to have the same strange side structure we have on the main runway at 13 50 27 north 16 39 55 west which on this shadow runway
appears at 13 21 31 north 16 39 33 west though on the shadow runway it appears to be heavily over grown and buried, it may simply be an area for
planes to turn around but is a very odd shape compared to how we do them today.
Of course even if it is ancient it does not have to be an airfield, it could be some ancient megalithic monumental or even astronomically aligned
ruin's that may have been reused and may point to an important but long lost west African culture having once existed in the region.
Or it could just be drunk surveyor's and very handy builders moving slabs of stone that seem too large for there small tractors and ww2 bulldozers to
have ever moved to create a stone build runway?.
Take a look over here at Blighty and indeed much of Europe and North Africa, Roman period road's and even settlement's have been continuously reused
over the century's while the far more primitive Celtic sites were mostly ignored, there is no reason that such pre-existent remains' may not have also
be reused by the local's there which creates something of a conundrum, how can you tell the old from the new especially when many of the structures in
a third world nation are not exactly modern or built as we would today.
It may be an impossible task to prove concisely one way or the other.
In more recent history this area fell under the control of several African empires that were highly advanced for there time.
And for comparison here are the remains' of an old concrete paved runway in the UK.
As you can see the slab's are large but no where near as large as those appear to be, of course closer inspection may show them to be actually
several slabs tightly joined together and that would explain it if that was the case.
