This is a block of concrete, etc, etc.

Am I right in thinking that it was rapidly sinking and the proposed arch couldn't be built on that ground and that the one in charge at the time wasn't happy..bobins wrote: 04 Mar 2024, 20:07 Mmmmmm. Concrete![]()

I have a feeling I've visited this place in Berlin in the past.

It's a VERY large concrete block.
......The Schwerbelastungskörper (German: "heavy load-exerting body") is a large concrete cylinder located at the intersection of Dudenstraße, General-Pape-Straße, and Loewenhardtdamm in the northwestern part of the borough of Tempelhof in Berlin, Germany. It was built by the bloke with the funny moustache's chief architect Albert Speer to determine the feasibility of constructing large buildings on the area's marshy, sandy ground. Erected between 1941 and 1942 it was meant to test the ground for a massive triumphal arch on a nearby plot.
.......It consists of a foundation with a diameter of 11 m (36 ft) that reaches 18.2 m (60 ft) into the ground and contains rooms which once housed instruments to measure ground subsidence caused by the weight of the cylinder, which was estimated as equivalent to the load calculated for one pillar of the intended arch. On this foundation a cylinder 14 m (46 ft) high and 21 m (69 ft) in diameter weighing 12,650 tonnes was erected at street level.

Give it a couple of hundred years and the archaeologists will be calling it the German Stonehenge.bobins wrote: 04 Mar 2024, 20:32 Although the concrete block sank a bit, I don't think it sank overly excessively. I seem to remember that something else got in the way of 'Germania' being built.....![]()

Somewhere I've got photos of the motorway tunnels that were built under the Tiergarten in Berlin - these were going to be part of the new Germania but there's actually only an isolated section of tunnels there - you access them from a manhole cover and go down a long ladder.
Here is an attempt...it can be done, not quite the focus required just yet.NewcastleFalcon wrote: 05 Mar 2024, 19:06 Wonder if anyone can create this sort of image with the optical properties of a wine glass using a bit of refraction.![]()
