This work is the result of a study trip to Albania that the author took in the company of architect Ramadan Aliu in September 2012. At that time, architect Aliu was a doctoral student at the Faculty of Architecture of the University of Sarajevo, and he worked on his doctoral dissertation (Comparative analysis of selected examples of cities in Macedonia and Albania) under the mentorship of the author. The city of Berat was one of the cities they visited. Apart from Berat, these were Butrint, Durres, Gjirokaster, Kruje, Shkoder, Tirana, Vlore and many natural sights such as the famous source of The Blue Eye (Syri i Kalter, for example). The aim of the study trip was to get to know cities on the spot and to contribute to the author's theory of „Architecturally Defined Space“ through their analysis (through 'cabinet work'). Berat is a city located in the central part of Albania, 70 kilometers south of Tirana and 71 kilometers north of Gjirokaster (Geographic coordinates: 40º42'29.68''N, 19º56'42.50''E, Elevation: 218 m). It developed on the foundations of the ancient Greek city of Antipateria (Greek: Ἀντιπάτρεια) which dates back to the 6th century BC. During the Byzantine period, the city was known as Pulcheriopolis. The Slavic name for this city is Bel(i)grad, which is known according to a medieval record from Grač (where the city is mentioned as Βελλέγραδα, i.e. Bellegrada). During the Ottoman administration, the city was known as Arnavut Belgradi, and today's name Berat was created by condensing this name from two words into one. The old core of the city consists of three parts: Kalaja (the fort on top of the hill), Mangalem (the city structure below the fort on the hill) and Gorica (a settlement on the left bank of the Osum River). Because of its vivid picture in which the buildings slide one behind the other on the hill, and where each of them 'captures views' of the Osum river valley, Berat is called the „City with a thousand windows“ (also „City of the Floating Windows“).
