The Selective Criteria for Trees in the Avenida da Liberdade, Lisbon 1882

This article explores the historical context and decision-making process behind the selection of tree species for Avenida da Liberdade, Lisbon’s iconic boulevard constructed in the late nineteenth century. The City Council’s decision to establish a grand avenue was influenced by Lisbon’s modernization, inspired by Parisian boulevards, and driven by the historical circumstances, particularly the reuse of trees from the Passeio Público, rather than the theoretical norms of the time that favored uniformity in tree species for their practical and visual benefits. The article examines three key aspects: the conception of the avenue as a symbol of progress, the work of the appointed committee and its decision-making influenced by the period’s scientific and artistic theories, and the specific tree species chosen, highlighting the socio-natural factors that influenced their selection. It argues that the choice of species, largely overlooked in historiography, reveals a nuanced interplay of practical constraints and urban planning ideals
