Abstract
Abstract The paper examines the urban growth patterns of two coastal fishing towns in southern Portugal: Olhão and Vila Real de Santo António. The goal is to investigate the relationship between the configurational and network properties of the urban forms in order to identify generative or emergent patterns, understanding their particular urban morphology. The Space Syntax Theory, applied to the syntactical modelling of these towns, is used to understand the urban processes. Topological variables, such as connectivity, integration and intelligibility, are calculated by DepthMap Software and the Theory of the “Deformed Wheel” is used to represent the evolutionary trends and to identify generic rules. The study is developed by comparing the two urban networks in two moments of their evolution, first in the mid-20th century, which corresponds to the historic core, and second corresponding to the present day. The main results demonstrate a contrast between the segregated network of Olhão's irregular historic centre and the integrated network of Vila Real de Santo António's regular historic centre, revealed by the value of integration variable. The urban expansion of these towns during the last decades decreased the value of integration and aggravated the intelligibility of the urban fabric. The application of syntactic approaches, with quantitative analysis, aims to complement the traditional procedures of the History of Urbanism, developing an operational method adaptable to the study of urban morphology.

Summary
The coastal fishing towns in Algarve, in the south of Portugal, have suffered an intense urban evolution during the last four decades. This research examines the urban evolution of two fishing towns on the coast of Algarve, Olhão and Vila Real de Santo António. By analyzing the configuration and urban shape according to the city’s model of the “Deformed Wheel”, defined by the Space Syntax Theory (Hillier, 2005, 2009), this research enables the morphological characteristics of the historic fishing towns to be understood. This real diagnosis of the evolution of urban towns links quantitative approaches to the traditional urban history analysis and develops a functional urban morphology method to use in future urban interventions
