The idea of an all-weather swimming pool is some thirty years old.
And a famous name stands behind the concept of that time.
The vision of a dome with openable segments
comes from the traditional firm Eiffel,
famous for its steel constructions.
The most spectacular and best-known structure in the world is the Eiffel Tower,
built in 1888 on the occasion of the World Fair in Paris.

The people at Eiffel developed Tournesol, a novel swimming pool concept
of an outdoor and indoor pool in one, in the 1970s.
The heart of the idea was the steel construction design in the form of a dome.

Tournesol^® was built some 180 times over the following years -
a figure that speaks for itself.

That is the past

When the patent rights belonging to the company Eiffel lapsed,
all of the rights to Tournesol^® were secured by a German company:
ARCH₂O in North Rhine-Westphalia.

And that’s when the future starts
