A new Dutch-language secondary school, Heilig Hart XL, will open on 1 September in Ixelles (Elsene), a municipality in Brussels, Belgium, housed in a still-under-construction multifunctional campus on Pleinlaan. The school, run by Catholic education group Katoba, was initially planned as a relocation of an existing institution but became a new independent school for financial reasons, and will begin with lower secondary classes before expanding its programme from 2027–2028. The opening is seen as significant for Dutch-language education provision in Brussels, with the campus also set to welcome upper secondary classes from nearby Atheneum Etterbeek.
