Villa Volta is an attraction in the amusement park Efteling in the Netherlands. It is a rare type of ride known as a Madhouse, which is a sort of haunted house, where the visitors get the illusion that either the building, the visitors themselves or both are turned upside down. It has been designed by Ton van de Ven and was built by Vekoma in 1996. At the time it was the first of its sort; nowadays the concept has been taken over by a number of other amusement parks.
