[4] The present castle was built between 1706 and 1712 by Gabriel-Henri de Mestral as a country residence with numerous outbuildings, including a theatre.

He had received the estate following a legal action, his uncle, the former owner, having initially chosen to donate it to one of his cousins Bernard de Budé.

He demolished it to rebuild on its ruins a French classical residence, with numerous outbuildings including an orangery.

The central avant-corps, which extends over three spans, is surmounted by a triangular pediment in which Mestral's sculpted arms are found.

The courtyard façade is similar, with the exception of its central front which occupies only one bay, also surmounted by a triangular pediment with the arms of de Mestral.

[14] These include the Corten steel sculpture My Twist by American artist Beverly Pepper as well as the installation of the Swiss Mireille Fulpius, a labyrinth of intertwined pine joists,[15] ten installations by Frenchman Christian Lapie representing characters made of burnt oak then oiled and painted black.

[16]  In 2018 sculptures by the Belgian designer Pol Quadens, the English Laura Ford, the Irish Dorothy Cross, the Spanish Carles Valverde and the Cuban Manuel Carbonell were added to the garden.

Elegantly vaulted, fresh as can be and with a floor covered with round paving stones, it contains six large oval oak vases with a total capacity of 73,000 litres.

These historic cellars were restored in 1979 by Gilbert Hammel of the house of the same name in Rolle, who has been managing the estate's vines and production since 1975.

[21] Restored, transformed and converted in 1998, the Collonges farm in Vullierens is now called "Portes des Iris" because of the six glass doors decorated with wrought iron that replaced the wooden ones that gave access to the stables and the barn.

Not to mention a gigantic garden terrace, with a view of Lake Geneva and the Alps, on which specific tents can be set up for major events.

In 2007, Portes des Iris was approved by the State of Vaud as an exceptional place for civil ceremonies.
