A country I would like to visit

If anybody ask me about what country I would like to visit, I'd say something like 'I can't say it, because I would like to visit the entire Europe instead'.
Once ago I heard about somebody saying that Europe was endless, I mean, it doesn't matter if you've traveled and visited it several times, seeing places, their countries and cities, there's always something new that you haven't seen yet. That's why choosing a country to visit from Europe it's a little complicated, I'll put and effort on it. I think I'd choose Germany, just to start with.
I'd like to visit Germany, I find it's a so distant country to me. First of all, it has a long history, cultural and political (I guess we all know a bit of that), but what I'm most interested is in seeing his architecture. Of course I have to visit the place where Berlin wall was placed, I've been searching and now there are parks where it was. And then I'd visit his ancient buildings like the church of St Mary, it is from the thirteenth century! Although has been changed through the times. Finally I'd continue until seen the most contemporary buildings, like the Bauhaus archive, the museum that collects documents and art pieces related to the Bauhaus school, one of the most influential schools of design and architecture of last century.
