Well.... the nose cabin looks like a Zeppelin - not a Hindenburg class but earlier - and as chevvron says no swastika so 1920's/early 30's looks good if it IS German.
Blowing up the second picture and giving it some computer "enhancement" the banner on the side of the central hangar looks like "Xaero" or maybe "Aero" - oddly there is a current Exxaero
https://www.exxaero.com/en based in the Netherlands. Doubt there is a connection but................... it does look pretty flat.
Above the main hangar it looks as if either something has been overpainted or our eminent ursine colleague has erased something - there is a large "S" just visible but the other letters I can't extract. Could be the name of the place, the owners of the hangar or just an advert.
