The Invasion of English into Europe

 English is becoming more pervasive into the European cultures, this is in Poland. This is another data point on a trend line that documents how people are choosing to incorporate English.

Now in this sign there is one English word that must be a very good simplification to force people to think it's better than the Polish version. 

 Language purists would get upset at someone using the improper words.  But memory of proper words lasts about as long as a lifetime.

Centrum is a Latin word, so should it be here in this Polish sign?
