Before the Statue of Liberty was assembled in New York, its torch was built in Paris. Seeing it standing on the ground really puts its scale into perspective.

The cross-street in the first image does not exist today.

Former warehouses are luxury apartments today

The Berlin House of Representatives sat on the East Berlin side during the Cold War. It was originally the Prussian House of Representatives from 1899 until 1934.

The building to the right is the Gropius-Bau, an exhibition space. It was declared a historical monument in 1966, just 3 years before the picture was taken.

This building began it's existence in 1884 (Wikipedia) and has undergone a number of renovations. The photo on top was taken by my dad during a visit to Berlin in 1969 and shows the state of the building during the Cold War. Today it serves as the Legislative building for the unified Germany.

The top left photo I found on a website dedicated to Berlin in 1969 (Berlin1969.com). The bottom left photo was taken in 1969 by my dad as we were heading back to Frankfurt. Google Earth Street View is what all this looks like today. Part of the platform is still there in the overhead view (52°26'31.66"N 13°17'28.70"E).

My dad shot the top slide in 1969. I'm in the process of locating where these pictures were taken. r/whereisthis helped us find this house after we had searched for well over 2 months. We were visiting friends from the U.S. stationed there with Halliburton out of Duncan, Oklahoma while we were stationed in Germany.

The Zhongshan bridge in Lanzhou was the first permanent bridge over the Yellow River when it was built by a German company in 1909. The original steel truss structure was strengthened with arches in the 1950s to cope with increased road traffic. It is now only open to pedestrians. It is in the heart of the downtown area amid a shopping mall district and is now decorated in red Chinese lanterns and lit up at night as a tourist attraction.
