ᐅ Unknown Pipe in the Garden and Concrete Cover

Hello,

We recently purchased an old house, built in 1980, north of Munich.
The builder passed away about 10 years ago, and the widow who sold it to us has not maintained the garden during that time and unfortunately cannot provide any information.

We are now trying to clear some parts of the garden to see what we can make of it.

While doing so, I noticed a pipe sticking out of the lawn – see first photo.
The pipe is hollow and quite deep. At first, I thought it was a parasol stand, but with a measuring tape, I reached a depth of about 2 meters (6.5 feet) and still didn’t find the bottom! It’s dry inside.

Other than the initial joke from colleagues about a “cellar” (by the way, I’m Austrian...), we have no idea what it could be.

Does anyone have any idea?

Additionally, we have found at least three round concrete covers (?) in the lawn so far (photo 2). One of them holds a heavy flowerpot, the others are overgrown. Are these simply foundations for pots, or something else?
There are no handles, openings, or anything similar visible.

Thanks for your help!

A friend of mine installed round pad foundations in his garden for gazebos that he regularly sets up for gatherings.
If you don’t know this, you might suspect all sorts of things behind them...

Why shouldn’t the threaded pipe have been used as an umbrella stand?

The house was built in 1980, which was still a time when people usually improvised. If you wanted to set up an umbrella, you wouldn’t drive to the hardware store to buy a special “umbrella mounting pipe DN75”... if a friend happened to have a 2-inch threaded pipe lying around, it would just be buried or driven into the ground, and that was it. The umbrella fits anyway.

In short:
You’ll only find out what those things really are for by grabbing a spade and digging to have a look.

In winter, our neighbor always places a suitable pole with a huge, heavy birdhouse on top into a concrete-set pole buried as deep as yours. It is installed this deep to prevent it from being blown over by storms.

Here, it's helpful to use some physical effort for exploration. Simply triggering the phone’s shutter probably won't be enough.

If it were a well, the widow would probably know. A water supply pipe would not be driven 2m (6.5 feet) straight down into the ground but only to the usual frost-proof depth. No one knows what someone was thinking by driving a water pipe more than 2m (6.5 feet) deep into the ground.

I would try to turn the pipe using a pipe wrench, also known as a spanner. Just throw away the concrete parts.

Whatever it is, it’s probably not practical to use. I would thoroughly wet the garden first anyway, and take the opportunity to tear both of them out as far as possible.

I’m not digging down more than 2m (6.5 feet), no way oO

I’ll try to test how deep it actually goes.

I’ll try to pry up the concrete pieces to see if it’s just a foundation or actually a cover for something.
