Discover the
true story of the Winter’s house

Welcome to the Winter House official website!

If you find yourself here reading, it’s probably because you’ve heard about the mysterious house “Casa Winter” in Fuerteventura. Perhaps you’ve also heard about its ties to nazi submarines, or about Gustav Winter, the German engineer that had the house built in the middle of World War II.

This is a Canary Islands story that should be heard around the world, but that in spite of the efforts of investigators and journalists, has remained obscured until now.

Some of you may have come across this historic case recently, and others perhaps have spent a long time in search of real answers.

In either case, we invite you to look through the different illuminating sections of this website, which offer information about the history of the house, who we are, and the project we’re working on.


The book “The Winter house” is the result of years of investigation and research, through which we have gathered shocking facts that until just recently were entirely unknown.

The reader will find answers to the enigmas that surround the house and its creator, explained in a clear, unambiguous manner, and accompanied by numerous images and blueprints.

The publication will be done this spring, an exact date to be confirmed soon.
