The Old Post Office was built in 1895 to accommodate the increased volume of mail passing through Pictou bound for Prince Edward Island and Quebec. This is a Victorian building with elements of the Georgian and Four Square styles built in sandstone with a copper sheathed roof. Apart from the imposing scale, the truly distinctive features are the dormers. The west dormer is unique, incorporating a chimney with a central window. The post office moved to a new location in 1956.
