The paper deals with the establishment and architecture of Austro-Hungarian monuments erected in Banja Luka in the period 1878-1918. The monuments were erected on the orders of the military administration, based on the reputation and tradition earlier seen throughout the former Habsburg Monarchy. The paper shows three monuments, only one of which is preserved, but in a state requiring significant interventions. The paper first presents the general historical framework, then the construction of the monuments, while the final discussion questions the relationship of contemporary society to these monuments and emphasizes the importance of inheriting the historical layers of architecture and the problem of the neglection of Austro-Hungarian heritage of military background in our country.

Churches with leaning arches have an important place in the architectural achievements of sacral architecture, from the early Byzantine period to the 19th century, in the larger area of the Balkans. The fact that a particular architectural type has existed for more than ten centuries shows its importance. They originated in the area where Eastern and Western influences collided, crossed and reconciled for centuries, resulting in specific architectural solutions that have been the subject of interest of researchers for a long period of time. They were singled out as a specific architectural type in the middle of the 20th century. They can generally be divided into two types; basic, simple and complex type. The basic type is evident throughout the whole Balkans, while the complex type is found in the territory of Herzegovina and Montenegro, area known as Old Herzegovina.
