Lunenburg is an old fishing village in Nova Scotia, about an hour west of Halifax. As a historic fishing town established in the 1750s, it has a lot of architecture that you would find in other fishing villages in the region, like in Maine or Massachusetts. Houses tended to be in a simple Cape Cod or Georgian/Federal architectural style. Some time in the 1800s, dormers were added to the center of some of these simple, boxy houses. The dormers provided light and air to the upper rooms, and gave some decoration to the simple architecture. These overhanging dormers became known as "Lunenburg bumps". The trend continued into other styles, such as with some Victorian houses. This vernacular architecture is found only in Lunenburg and some surrounding towns.
