The Umpqua River Lighthouse, built in 1894, is constructed of brick. This is evident by the adjacent picture showing the inside wall. During my tenure as a tour guide at this lighthouse, many people commented about the brick color on the wall. First impression for some was that recycled brick were used to build the lighthouse. Although the brick does appear to be recycled, this is not the case.
Several years after the lighthouse was built, in an effort to reduce maintenance of the inside wall, it was painted white. However, this action later proved to be a mistake. The brick of the inside wall could not breath to the airspace between the inner and outer walls. This created a problem with condensation on painted surface of the inside wall. Engineers later concluded the paint had to be removed. This was done by carefully sandblasting the paint without damaging the brick surface. That action left the wall with the appearance of being built with recycled brick.
