From the upper floor of Niebert Windmill you can walk out onto a hexagonal platform circling the windmill. However parts of it are sectioned off so that you cannot fully walk round it.

This video of the sails shows why access is restricted. They could take your head off or throw you off the platform:-

A view from the platform:-

Another view, showing flag of Groningen Province:-

Niebert is a village in Groningen Province, The Netherlands. Its windmill also had an open day while were were there last June.

Windmill:-

Sketch of how a windmill works:-

I spotted these in a display case inside the  Windmill. At first I thought they might be cigarette cards but no. They are matchbox cards:-

Interior:-

Gearing wheel:-

Stairs. These were quite scary to ascend:-

And to descend!:-

Upper floor:-

Inside Sebaldeburen Windmill there were several windmill related displays.

Models of windmills:-

Another set of windmill models had electrically driven sails:-

Cutaway model:-

Collectables:-

Hanging embroidery depicting various Dutch windmills. (Hanging embroideries like this seem to be a Dutch thing):-

Pictures of windmills:-

Windmill shaft. Note thatch on walls:-

Apparatus:-

Steps. We would call this a ladder really, but stairs in Dutch houses tend to be very steep:-

One of the walls on the upper floor had a couple of paintings of the windmill:-

View from window:-

And as a plus here’s a video of the outflow into the canal:-

I posted photos of the windmill’s exterior here.

Internal machinery:-

Again this video is on its side:-

There’s a glass “window” in the windmill’s floor so that you can see the water flowing under it:-

Video. The flow is quite noisy:-

There were live cams round the windmill with their feeds displayed on a screen:-

The Netherlands are famous for windmills but though we had been in that country several times we hadn’t actually visited a windmill there till last June. It was the one at Sebaldeburen in Groningen Province. There was some kind of open day on so we could see inside.

There is a model of the windmill just at the end of the drive:-

In this photo the operator is adjusting the angle the windmill makes with the wind to maximise efficiency. Windmill model to right:-

The windmill lifts water from a ditch (to the left in background) into a canal 1½ metres higher (to the right) by means of an Archimedes screw. A full size model of the screw is at left of photo.

The canal:-

This is the Archimedes screw in operation:-

Windmill turning. For some reason the video is turned by 90 degrees:-

For some reason there are art installations studded along Dutch motorways. This one shows a concrete elephant.

There are several of them!

No visit to the Netherlands is complete without a photo of a windmill. This one is right beside the motorway we travelled back by.

This is the same windmill from the reverse angle.

This is not quite typical of modern Dutch commercial buildings but they do seem to like curves.

The same building from the side is revealed to be inhabited by KPMG.
