Lots of turrets to be found, some had extra "boxes" sticking out of upper floors.

Notches in random places were also popular.

Buildings which look like marine vessels were another favorite. This one looks very much like a submarine. We saw others that looked like large ships.

This one was a puzzler: The whole thing was covered with thin spiderweb like metal railings, and what looked like a shale rock garden.

This one was down the street and continued the spindly metal look. There must have been a bunch of architects doing acid at some point in Berlin's past!

The "Info Box". This was a giant box (it's about 60 feet wide and 50 feet tall) standing on stilts which raise it 40 feet into the air. It's right in the center of a massive construction zone in the new center of Berlin. We counted over 40 giant construction cranes as we looked around from the top of this building. There were also diagrams of the city center with the outlines of the new buildings overlaid. We both would like to come back in five years and see how different things look.

Some of the fun building shapes in the city center.

Notice that green block perched way up in the air...

The panorama from the top of the "Info Box". There were at least a dozen building cranes visible anywhere you look.
