The structure of Tvrđa and its buildings date back to the Middle Ages. Tvrđa represents the Old Town of the city of Osijek and the best-preserved and largest ensemble of Baroque buildings in Croatia. After the withdrawal of the Ottomans in 1687, during the 18th century, the Austro-Hungarian administration systematically formed a new fortification system, regulated streets and squares and built a large number of military objects. Tvrđa took its present form in the 19th century and has kept it since then. Investigating the historical development of individual buildings, in addition to archival sources and existing architectural documentation, the obvious source of information are the buildings themselves. The aim of this paper is to explore the possibilities of using infrared thermography to find structural elements and hidden openings in historic buildings in Osijek’s Tvrđa. This paper describes the exploration of the 18th century openings on the facades of the former Kostić houses. The facades were bricked into the walls in the 19th century because houses were reused and their purposes changed from commercial to residential. Infrared thermography is often a starting, nondestructive testing method (NDT) for building analyses. This paper presents thermographic analyses of two buildings. The analyses were carried out in December 2017 and January 2018. Using a steady-state thermographic analysis of a building envelope as the first step, the audit was continued with step heating (SH) of an interest point where changes in a thermal pattern were expected due to additional bricking. Heat flux was generated by the usage of a heat gun for paint removal.

U radu se donosi detaljan pregled nekretnina koje je u dubrovačkom burgusu posjedovala vlasteoska obitelj Mençe tijekom 13. i u prvoj polovici 14. stoljeća. Prati se međusobna povezanost obiteljske strukture jedne od najutjecajnijih obitelji toga razdoblja, urbanoga razvoja grada te političko-društvenih okolnosti. U radu je primijenjena metodologija istraživanja socijalne topografije u urbanoj povijesti.

This paper focuses on the spatial distribution of Dubrovnik’s urban elite, observed on the examples of the families of Matijaš de Mençe and Anđelo Ljutica, in the period from the late 13th to the mid-14th century and the time of Black Death. Using the methods of social topography and prosopography, the authors have studied the interrelation of the social and ownership statuses of these families, addressing the question of their social and spatial interconnections. In the early 14th century, both families belonged to the elite urban circles, but with a key difference: one of them was noble, and the other a family of commoners

Na temelju dosadašnjih istraživanja, prostorne analize, pisanih izvora i rezultata arheoloških istraživanja u ovom ćemo radu ponuditi hipotezu o fazama oblikovanja prostora dubrovačkoga predgrađa koji se transformira u središte grada tijekom 13. stoljeća, a danas u sebi nosi veliku slojevitost stoljetnih promjena. Komunalno planiranje predgrađā počinje već u prvoj polovini 13. stoljeća, prije promjena zabilježenih u regulacijama ulica 1272. i 1296. godine, a na prijelazu u 14. stoljeću kulminira unificiranjem različitih cjelina u jedinstveni prostor.

U članku se razmatraju prostorne i oblikovne značajke stambene arhitekture Osijeka u 18. stoljeću. To su većinom građanske kuće obrtnika, trgovaca, gradskih i vojnih činovnika, koje nastaju na parcelama unutar planski izgrađenoga grada-tvrđave. Kuće...
