Saint-Hyacinthe

A seigneur's patron saint

Saint-Hyacinthe in brief

Saint-Hyacinthe sits east of Montreal on the Yamaska River in Montérégie's Les Maskoutains. Jacques-Hyacinthe Simon dit Delorme began settlement in 1757 and named the seigneurie for his patron, Saint Hyacinth the Confessor of Poland.

City status arrived in 1850. St. Hyacinth's Cathedral, seat of the diocese since 1852, remembers Bishop Louis-Zéphirin Moreau, later beatified. In 2001 five neighbouring towns joined the Maskoutain centre.
