Salama1, Department of Architecture, University of Strathclyde, Glasgow, UK Adel M. Remali, Department of Architecture, University of Strathclyde, Glasgow, UK Laura MacLean, Department of Architecture, University of Strathclyde, Glasgow, UK Urban open spaces have substantially contributed to the development of cities in terms of image, function, form, and social engagement, and thus have been a central concern of urban researchers for several decades. This paper contributes to the contemporary urban discourse as it relates to the city and its users. It demonstrates a mechanism for characterisation and systematic assessment of key urban open spaces in Glasgow City Centre. The mechanism is implemented in three layers of investigation that involve the development of space profiles through preliminary observations, an examination of functional, social, and perceptual attributes through a walking tour assessment procedure with checklists and a scoring system, and an understanding of how users perceive and comprehend these spaces through a photographic attitude survey. The paper places emphasis on key findings by conveying similarities and differences between the spaces in terms of assessment outcomes and users’ perception, while revealing their essential attributes and qualities. Conclusions are offered as reflections on the findings while suggesting possibilities for future research through additional complementary layers of investigation. Key words: urban open space, walking tour assessment, users perception, urban space attributes, Glasgow.

Such a mechanism enables a profound insight into the understanding of the essential characteristics of urban open spaces. THE CONTEXT OF THE Study: Glasgow CITY CENTRE The City Centre of Glasgow can be understood within three main stages of development: The Medieval City, the Merchant City, and Blythswood. The medieval stage began in the 12th century with the centre fully established by the 16th century (McKean et al. the medieval Cathedral that has prime importance to the city (Williamson et al., 1990)., 1989). The second The only stage remaining was the edifice planned is in 1786.
