I'm looking for some tiles. Where can I find them?

[Nbg]

I've googled them but have had no success apart from being taken to forums where other people are looking for them too.

All that I can find written on them is "Gres Monococcion" and "Made in Spain".
They are about 12" by 12" and look a bit like bricks on them. They are floor tiles.

Has anyone had to do something similar before?

are they terrcotta?

Errrr not sure.

When I did a translation of Gres Monococcion, it means Stonebake something or other

I searched all night to no avail.
