Tema su ovoga rada arhitekti, graditelji i mjernici (geometri) na prostoru grada Mostara u razdoblju austrougarske uprave, ali i u posljednjem razdoblju osmanske vladavine. Otkrivene su njihove biografije, pozicije koje su zauzimali u graditeljskoj strukturi i autorstvo nad objektima ili urbanistièkim potezima. Utvrđeni su uvjeti unutar kojih su radili, zakonodavno-pravni okvir i metode rada koje su dovele do promjena slike grada. This paper presents the Mostar-based architects, builders, and surveyors in the period of the Austro-Hungarian Monarchy as well as in the last phase of the Ottoman Empire. It looks at their biographies, professional positions and authorship of some structures and urban planning interventions. It also analyses their professional work in terms of the circumstances, legislative and legal framework, and methods of work that eventually changed the image of the city.
