The Library’s iconic dome is the first of its kind in Canada. The span of the dome was exceptional in 1876. With 32 iron ribs and plaster infill, it continues to shine bright gold today. #LibraryParl150

Le dôme emblématique de la Bibliothèque est le premier du genre au Canada. En 1876, la portée de ce dôme était exceptionnelle. Composé de 32 nervures en fer et d’un remplissage en plâtre, il brille encore aujourd’hui d’un éclat doré. #BiblioParl150
