Opposite his dyeing factory the foundation stone of a magnificent country residence is laid in 1971, which will carry the name "Schloss Blumenthal" and to his own description is located "Im Lugenthal". After only several months of well-earned rest in the still not fully completed building, he deceased on the 5th of december 5 1795
After the death of his father, son Adam kept on building on the not yet completed Blumenthal. Because of the weak economy at the time of the French Revolution, the "house" has been in different hands and in 1846 Aachens councilor Joh. Wilh. van Lommessen bought the house. He gave the building to the religious order "Dames du Sacre Coeur", which his both daughters, Anne and Caroline, had joined.
Bloemndal built great fame within the Catholic boarding schools in Europe and even beyond. Rose Kennedy has even been here eat boarding school. During the occupation which lasted from 1940 to 1944 the building was commandeered by the occupying forces and used as a military hospital with a capacity of 350 beds. From 1947 onwards the boarding school, now under the Dutch name "Klooster Bloemendal", continued to operate at full capacity until early 1970, when both the number of pupils and the number of vocations began to decline. 1976 saw the end of almost a 130 years of convent life and in 1978 ownership of the property passed to the municipal Vaals.
In November 1990 the municipal Vaals and Van der Valk, in cooperation with the Province of Limburg and de Dutch Historic Building Trust, agreed to restore the complex, which had been standing empty for some considerable time and had fallen into serious disrepair and covert it into a luxury hotel. This highly succesful collaboration has restored the old Schloss Blumenthal to its former glory, and a building of great cultural and historic value has been preserved in a fitting manner.
