Road signs in Catalan
I was in Palma, and I took this picture.
Although not everyone speaks Catalan (and a sizeable minority speak Spanish) the sign is only in Catalan, and there was not
an equivalent in Spanish to be seen.
If you happen to have a car, it is quite useful to know what it means.
So, go learn the days of the week, and don't get fined. Start lesson
This notice is a reminder that Catalan is being spoken all around you. Anyone can forget this as a visitor.
It is easy to visit Mallorca, speak in Spanish (or English, German or Polish) and not even realize (or know) that there is another language being lived all around you.
