I think about an common initiative of the country members of EU, to create a museum in each country, with multimedia support to share ideas, nowaday culture and language, connecting people of Europe.
The mesuem can call the "Common House", thinking about the common heritage, a piece sharing in these areas.
Each country cares about the local space and the areas in each other spaces of Europe, related with its entitlement.
A common area is cared by EU.
These museums are relised using multimedia technology for a continuous update and a remote interaction.
