The Waite Brick Block, a historic commercial building at 422-424 Main Street in Malden. Built in 1848, it is the oldest brick building in the city. Note this Greek Revival building’s hip roof, from which three tapered chimneys project. One corner of the building is curved, following the original junction of Main and Pleasant Streets. Granite lintels top the windows, and the cornice has a line of brick dentil work. These are classic characteristics of commercial buildings of the time in New England.
