How Long Is Opalescence Good

Architecture Day - Broaden your horizon

See: http://www.denkraum-architektur.de/

For the day of architecture in Germany I have invited some fellow colleagues
to talk about their architecture. The event will take place
in the rooms of the museum in Dresden Erich Kaestner.
Their will also be a workshop for children about bee's and architecture.
A beekeeper will be present and we can eat honey and bread.
