Tonny Zwollo

Zwollo was appointed as a consultant in 1996 by Diódoro Carrasco Altamirano, Governor of Oaxaca, for special projects. One of those projects, at Hierve el Agua, created the pools at the ancient canals. Previously, swimming had been forbidden to protect the archaeological heritage of the site, but with the building of the pools, the local community was able to improve employment of local inhabitants through the funds earned by tourism. She created a documentary film, Blue is my colour: designing as an answer to nature about the project.

As her final student project in 1970, Zwollo went to Ecuador to design the Otavalo Market. The market is the largest outdoor market in South America and was not completed until 1973. She built 90 concrete market stalls to create the Plaza de los Ponchos and house the handicrafts of indigenous merchants. She completed her dissertation entitled, Fantasy and architecture, and it was published in English, Spanish and Dutch in 1975. In 1976, Zwollo returned to Oaxaca and worked on a collaborative project to restore the Santa Catalina Convent with architect Martín Ruíz Camino. The conserved sixteenth-century, ex-convent was converted into a five-star hotel called El Presidente, winning Zwollo an additional Prix d'Excellence Award, from France.

Tonny Zwollo (born 1942) is a Dutch architect who has worked since 1964 in the Americas. In addition to designing and building over 35 schools in Mexico, she designed the largest indigenous market in South America, in Otavalo, Ecuador. Her approach to architecture is to build what is useful for the local community. Besides schools, she has built a hotel, tourist villages and a swimming pool to boost employment of residents in Oaxaca, Mexico.

Tonny Zwollo was born on 1 February 1942 in Amsterdam, the Netherlands. She was the daughter of the goldsmith, Marinus Zwollo. She graduated in 1964 with a degree in architecture from the Delft University of Technology, but found it difficult to find work as a female architect in the Netherlands. That same year, Zwollo accepted an offer to work for the Mexican government building schools. Initially employed in Mexico City, she found bias against working with a woman there too and requested that she be transferred to more remote areas. She was sent to Oaxaca, where she had to convince the local villagers to work for her, without pay, to build the schools for their communities. Often, to get supplies to the sites, they had to build airstrips as well. Within two years, she had built nearly 30 airstrips and 35 schools. Her work was featured in Life magazine in 1967. She completed her work with the Mexican government in 1968, graduated in 1970 with a degree in engineering and received the Prix d'Excellence Award for her work.
