Her soft landing meant the mare escaped without serious injuries, but she had to be winched out of the caravan by a team of firemen.
According to a report in the Niederösterreichische Nachrichten the 28-year-old mare, known as Netti, broke out of her paddock during the night and wandered down a hillside which is directly above the mobile home.
Part of the slope, which forms a roof over the caravan, is made of corrugated metal which wasn't strong enough to hold her weight, so she went crashing through it and the roof of the caravan.
She was lucky to land in a double bed. "If she had fallen onto the concrete she wouldn't have had a chance,” her owner, Jacqueline-Isolde Bauer-Weiskirchner said.
Bauer-Weiskirchner discovered Netti was not in the paddock and heard the sound of hooves knocking against the walls of the unoccupied mobile home.
She called a vet, who gave Netti a sedative, and a team of firefighters who spent some time trying to get her out of the bed, with the help of mountain rescue equipment.
The next day Netti was judged fit and healthy and allowed back onto the pasture to graze.
