[OSM-talk] How to tag a Spanish-style central plaza?

[Mike Collinson]

Is anyone mapping in continental Europe using a tag for the following feature?

In Mexican Spanish it is el zócalo.  A central 
square or plaza in the centre of a town or 
village generally laid out with paved walkways 
and flower beds and is an important part of social life.

The English words "square", "plaza"  or "park" 
may be too vague.  I want something that implies 
"this is the formal centre of 
town".  leisure=zocalo would be perfect but probably too colloquial.
