In 1927, the exiled Tsarist Colonel, Nicolai Woevodsky and his wife Dorothy Webster, an English Aristocrat fond of decorating, were looking for a Mediterranean paradise in which to settle down. Close to Calella de Palafrugell, on a cliff above Cap Roig, they built a castle which would connect them to this spot for the rest of their lives (they even asked to be buried there). The building was surrounded by an idyllic botanical garden, considered one of the most important in the Mediterranean.

Nicolai himself designed the mansion in the neo-medieval style (imitating the Monastery of Poblet), construction of which began in 1931 and was completed in 1975. It was popularly known as "Cal Rus" (the Russian House) after the origins of its owner. However, the couple always lived at the property which gives access to the botanical gardens. This is the main legacy of Dorothy Webster. She and a team of gardeners from the region took charge of preparing the seven hectares of land in order to plant various species. In 1935 there were more than 500 species of Mediterranean, tropical and subtropical flora.

When the couple died, the estate passed to the Fundació Caixa Girona and then to the "la Caixa" Foundation, which turned the land into a sculpture park for contemporary artists with works by Jorge Oteiza, Jaume Plensa and Xavier Corberó. Every summer the gardens are home to a prestigious concert series: the Cap Roig Festival.
