Mind you those Prague sett pavements are indeed Portuguese pavements.
Portuguese pavements are found all over the world. You can find them all
over the old Portuguese empire, but also in Hong Kong, Shanghai,
Beijing, San Francisco, Honolulu, Prague, Spain, Brussels, Gibraltar, etc.
The hand carved and laid stones, with its characteristic patterns is a
well documented style, which was developed by the Romans and the Arabs
and was perfected and adopted in the XV century. It has a proper design,
geology and colour pattern and it's very easily recognized when you see it.
It's a ubiquitous feature in Portugal and Brazil, and it needs a tag to
differentiate it from other pavements, not only due to its artistic
features, but also for statistical data and mobility purposes.

A mosaic it's not a correct description, because it's a pavement, not a
touristic or artistic feature per se.
