A fake Dutch nun donated centers where she managed irregular adoptions during the dictatorship to the Integra Foundation: today they are kindergartens.

5 September 2025

Between 1970 and 1990, Geertruida Kuijpers not only arranged irregular adoptions of Chileans to the Netherlands, but also purchased a large number of properties to operate in La Cisterna and Buin. In the 2000s, she donated a large portion of the properties to the Integra Foundation, while selling others to Jehovah's Witnesses and her former right-hand man in Chile.


Despite the passing of years, the story of Geertruida Kuijpers, who arranged irregular and illegal adoptions from Chile to the Netherlands, continues to be written. A well-known fact, but one that has not been fully explored, is the donations of real estate that this fake Dutch nun made to the Integra Foundation in the early 2000s. 

Specifically, these were six properties that Kuijpers acquired in the 1970s and 1980s with cash payments and then, thirty years later, without his personal motivations being known, were transferred to the institution. 

In this context, four properties located in the El Bosque district of Santiago were donated: one on Caminos de Chile Street and three in Los Aviadores, donated in 2004. 

In addition, Kuijpers had his own foundation called Stichting Kindertehuis Las Palmas Foundation, which he also used to manage donations, but in Buin. One was located on Calle San Martín and the other in Balmaceda in 2005. 

Currently, the buildings at Los Aviadores 1134 and San Martín 245 continue to operate as Integra kindergartens and daycare centers, retaining the foundation's name, Las Palmas, until at least 2018.

With Kuijpers's death in January 2023, questions remain about the reasons behind her decision to donate the properties, as well as how they were paid for and whether their acquisition was related to the funds she received from the adoptions she carried out.

Along these lines, Interferencia had access to a financial report from Las Palmas dated September 1984. The document details a purchase the foundation made from a Dutch congregation in 1983 for 85,000 Dutch guilders (43,000 dollars at the time) and that a total of 30,900 guilders (12,460 dollars) was allocated for equipment and renovation. 

Regarding the foundation through which Kuijpers made the donations, this editorial team was able to review a deed containing the institution's bylaws, which indicates that the Stichting Kindertehuis Las Palmas was also registered in the Netherlands and legally constituted. 

According to this document, the headquarters were located in the municipality of Barendrecht, the same town where Bastiaanse Kuijpeers, the sister of the fake Dutch nun, lived. A source who testified to Interferencia claims that the foundation's money passed through the board of directors, which also included Bastiaanse Kuijpeers.

Regarding the role of the Integra Foundation, this media outlet was able to review a response the institution provided to a private individual who inquired about these donations. 

Specifically, they point out the following reasons: "Fundación Integra has no information regarding the motivations of the individual and the donor institution in the aforementioned contracts. The very nature of this type of contract, contained in the legal norms that regulate the subject matter in Chile, does not require an express motivation that must be reflected in the agreement." 

Regarding the value of the properties, they explain: “The background information on the value of the aforementioned properties at the time of the donation is only contained in the 2004 deed. It corresponds to the fiscal appraisal set by the Internal Revenue Service (SII) at the time of the judicial insinuation process [...] According to the 2004 deed, the appraisal of the El Bosque properties totaled $158,813,731. The 2005 deed does not include this detail. In both cases, the courts declared that the donations were exempt from tax.”  

The Kuijpers houses

The San Miguel Real Estate Registry lists four properties that once belonged to the Las Palmas Foundation, all located in the former State Transport (ETC) settlement, in the former commune of La Cisterna, which is now El Bosque.

In 1979, Kuijpers purchased the properties at Los Aviadores 1166, 1150, and 1134 on behalf of the Foundation for $250,000, $40,000, and $40,000, respectively. The following year, 1980, he purchased the house at Caminos de Chile 10007 for $200,000 cash. 

The four properties were donated to Integra in 2004, under judicial decree 13.054-2003. Interestingly, the deed kept in the Santiago Judicial Archives states that the Las Palmas Foundation only owns the property on Caminos de Chile, while Kuijpers is listed as the owner of the remaining three properties in Los Aviadores.

However, there are also two other properties that did not end up in Integra's hands. These are lot 171 and lot b of lot 170 in block H of the ETC subdivision, which were acquired by Las Palmas for $400,000 and $265,000 in 1982. According to records, both properties were sold in 1994 to Jehovah's Witnesses for $7 million and $2 million, respectively.

Meanwhile, in the Buin Registry, four properties are listed in the name of Las Palmas.

The two properties that ended up in Integra's hands were purchased in 1983. That year, the foundation registered a property located at 245 San Martín Avenue and a lot at 25 Balmaceda Street, which it purchased from the Dutch Congregation of the Brothers of the Immaculate Conception for $750,000 in cash. These funds were donated to Integra in 2005.

But there are also two other properties that are the only ones that did not end up in the hands of the State. 

These are two houses located in a closed passageway at 236 Bernardo O'Higgins Avenue. The first, marked House No. 1, was purchased in 1999 for 2,300 UF, approximately $34 million. The second, House No. 5, was purchased for 2,450 UF, approximately $38 million. Both were acquired from the Canepa Gómez e Hijos Limited Affordable Housing Construction Company.

Just one year later, in 2001, Las Palmas sold House No. 1 to María Angélica Crystal Arce Couso, Kuijpers's right-hand woman at the children's home, for the same $34 million for which she purchased it. The same fate befell House No. 5, which Arce Couso purchased from the foundation for $38 million.

In 2009, House No. 1 was purchased by Crystal Elizabeth Oisel Arce, daughter of Kuijpers's right-hand woman, for $32 million. In 2020, it changed hands again, with $70 million given in lieu of payment to Oisel Arce's cousins, under the pretext of "the expenses the buyers have incurred due to the seller's precarious health."
