Urban Open Spaces in Historical Perspective: A Transdisciplinary Typology and Analysis

Abstract
Urban open space provides a unique conduit for the sociospatial study of urban history. We propose seven categories to help scholars historically situate and analyze urban open spaces: food production areas, parks and gardens, recreational space, plazas, streets, transport facilities, and incidental space. We use these categories, and the contrast between grey and green space, to compare examples from archaeological, historical, and recent times across a broad geographical range. Top-down and bottom-up actions dialectically intersect in the establishment, use, and reproduction of urban open space, and many open spaces prove to be particularly flexible in serving the general population. These findings can inform comparative urban analysis, and they help contextualize current debates concerning the socioeconomic, political, and urban ecological functions of open and public spaces.
