On Thursday 15 October 2026, Luxembourg's Ministry for Mobility and Public Works announced that the Chamber of Deputies had approved a €210.6 million (including VAT) investment in a new campus for the International School of Mondorf-les-Bains, including a boarding facility.
Construction is expected to begin at the end of 2027, with the school scheduled to open for the 2031/2032 academic year.
The bill, submitted by Luxembourg's Minister for Mobility and Public Works, Yuriko Backes, aims to address expected demographic growth in the southeast of the country, strengthen the region's educational offering and support its long-term development.
"Anticipating the needs of a growing population means investing today in quality infrastructure that will enable future generations to learn, develop and succeed. This project will sustainably strengthen the educational offering and contribute to a more balanced distribution of schools across the country," said Minister Yuriko Backes.
Population projections for southeastern Luxembourg indicate a significant increase in the number of pupils in the region by 2030. To meet this demand, the government decided to develop a new school campus in Mondorf-les-Bains, in line with national educational infrastructure planning.
Established by the law of 13 July 2018, the International School of Mondorf-les-Bains has welcomed pupils at a temporary site since the 2018/2019 academic year. In response to growing demand, the school has progressively increased its capacity through modular facilities, noted the ministry.
The future campus, located at the "Um Gréimelter" site, will bring together a primary school, European secondary education, Luxembourgish secondary education and vocational training. It will have a capacity of 1,690 pupils across 78 classes.
The project also includes a boarding facility with 43 rooms, primarily intended for pupils attending the school. Some accommodation may also be made available to athletes participating in training camps at neighbouring sports facilities, allowing for more efficient use of the site's public infrastructure.
The campus will benefit from good accessibility, particularly by public transport, and will form part of a wider complex bringing together educational, sports and municipal facilities.
The buildings will aim to achieve an A-A-A energy rating and will feature photovoltaic installations covering a significant proportion of their energy needs. The project also includes measures to promote responsible water management, biodiversity and the creation of outdoor spaces for educational activities and recreation.
Luxembourg's Public Buildings Administration developed the project in cooperation with the Ministry of Education, Children and Youth, the Ministry of Sport and the Municipality of Mondorf-les-Bains. According to the government, this collaboration has made it possible to design a site that encourages complementary use of the different facilities and efficient management of public resources.
