I've created a custom map on GOOGLE MAPS : modern and comtemporary art places in the WORLD.
this map groups exhibition spaces for Modern art (art from 1907 to 1960), Contemporary art (art from 1960 to today) and Street art.
here is the adress :mapsengine.google.com/map/edit…
send me a note if you want to participate (In order to authorize you to modify the map I need a gmail address).
or you can consult
it (don't forget to bookmark the page) just as an easy tool to discover new museums, gallery or artist's studios
hope you enjoy !
