Within a 10 minute stroll one will find Venice (including a horribly loud singing gondolier) Berlin, Munich, the Netherlands, and much more. There are so many details and even the (real) plants are miniaturized. Here the pic's!
Red Townhall, Berlin
The Bridge of Sighs, Venice
Carnival in Venice (There is music and the little figures move)
City of Frankfurt
Soccer Arena in Munich
My son's favourite: Starwars
