Is it usual that domestic mains electricity in Spain isn't grounded?

We're getting it grounded at home, which I thought might be an anomaly, but now I'm in the library and getting the same tell-tale tingling sensation when running my fingers along the surfaces of my laptop.

@blag I just bought a home in a building from the 60s. The outlets have fuses and the building itself doesn't have a ground take. More recent buildings are correctly grounded but many older ones aren't. I'll probably see about getting one installed, though.
@nirro Ours in mid 1970s I think, so I guess could fall the wrong side of any subsequent requirements to earth the mains.
