Richard Haag - Gas Work Park, Seattle, 1971-1988
In landscape architecture, history was invoked as a means to create specificity and uniqueness, especially on postindustrial sites, an early example being Seattle's Gas Work Park (1971-88) by Richard Haag, where the relics of a gasification plant were preserved. By drawing on the past uses and materials of a particular place, landscape was conceptually understood as a cultural palimpsest - as one layer among many - rather than a tabula rasa, as had been the case during industrialization. Even on sites where all previous material traces (both natural and cultural) had been erased, history became a way to engage place as designers took inspiration from a site's past (such as previous geometries or materials) to inform their designs.
