The castle was bought in the late nineteenth century by a Cholet industrialist , Mr. BERGéRE. At the request of the owner, architect Alexandre MARCEL restored the interior and arranged the surrounding landscape.
Between 1899 and 1913, he created an eastern area with a strong Japanese design,
From this period, the park was converted into agricultural and forest farming and progressively planted with trees up to 1980. After 40 years, the 29 ha of the current ownership were completely laid fallow, the walks completely overrun with brushwood and instead of the major alleys of the past remained walks of about 1 meter wide. Works (lanterns, bridges, pier, temple, pagoda...) were in ruins or had even disappeared.
The town council of Maulevrier bought the park in 1980 and the park was listed, in the same year, as the sites. An association was created to ensure the management and the maintenance of the park. Using documents, photographs found and other evidence, its restoration began. Originally called Association Castle Park Colbert, the association took the name Oriental Park in 1985. These were the first volunteers of the association who undertook major work within the park.
In 1987, Japanese professors from the horticultural universities of TOKYO and NIIGATA recognized the 12 hectares of the classified site as Japanese- gardens inspired of the period EDO (XVI-XIX centuries).
Since that date, major projects have been started and are still continuing today. The park is now recognised as the biggest Japanese inspired park in Europe and is a pilot project in Europe for the quality of its restoration and enhancement.
These projects, the work and activities are carried out by an association (Act 1901) made up of volunteers, a permanent team of professionals and apprentices.
