When the subject is the place itself
A building offers another kind of source material.
Architecture may provide the obvious starting point, although the identity of a place is rarely contained in its façade alone. A date stone, gate, garden, boundary, view or small architectural detail may say just as much to the people who know it.
There may also be records associated with the place: deeds, plans, handwritten notes, or fragments of its history. The interesting part is deciding which of those references carry the story.
A plaque does not need to catalogue everything about a place. It can bring together selected details from different times and different sources, allowing the finished composition to express something of how that place is known and remembered.
Part of the surroundings
Perhaps the most interesting question is not simply what belongs on a wall plaque, but where the plaque itself belongs.
Clear glass can borrow from what lies behind it. Black glass can introduce a strong graphic object into a room. Timber can establish a relationship with existing materials and history.
Artwork can respond to those characteristics, just as the choice of plaque can respond to the artwork.
And once installed, the surroundings continue to interact with the finished piece. Light changes across the glass. Reflections and shadows move. Clear areas reveal the wall behind. Layered engraving shifts slightly with the viewing angle.
A wall plaque may record a place, an achievement or a memory.
Over time, it also becomes part of the place in which that story continues to be seen.
