Issued in 1975, this Belgian stamp commemorates the Université Catholique de Louvain (UCL), one of the oldest and most prestigious universities in Belgium, originally founded in 1425. The design features the university’s historic seal depicting Sedes Sapientiae (Seat of Wisdom), symbolizing the Virgin Mary seated with the Child Jesus, an emblem of knowledge and enlightenment. The Latin inscription “UNIVERSITAS CATHOLICA LOVANIENSIS: SEDES SAPIENTIAE” surrounds the image. The blue and white background adds solemnity and academic dignity to the composition, reflecting Belgium’s respect for learning and tradition.
