The topic of the thesis is the the modernist architectural achievement of Rikard Marasović in Krvavica, near Makarska. The Yugoslav People's Army received land in Krvavica from the municipality of Baška Voda, and in the early 1960s, the construction of the health resort began. The circular, floating volume architecture on the „L“ block was built for the purpose of treating respiratory disorders in the children of military personnel. The building became a military resort in 1973, when its primary health purpose was converted to tourism. The resort remained in this function until 1991, when the Yugoslav People's army left the facility, and it became the property of the Croatian army and a home for war refugees. The building was demilitarized in 2000, when it became the property of the state agency Club Adriatic. Through privatization, supervision over the building was removed, which resulted in the destruction and deterioration of the unique modernist architecture. Miranda Veljačić's published research in the magazine Oris dispersed knowledge of the existence of this building, which further encouraged numerous associations, activists, and individuals to engage in the process of protection and preservation. Thanks to the efforts of individuals, the building was preliminarily protected in 2012 and then placed under permanent protection in 2015. The thesis critically examines the process from the beginning of construction to the current status quo in a methodologically interdisciplinary manner, building on a socio-historical-artistic basis, as suggested by the title. It brings together previous research and scant written documents in one place, interweaving them with new facts and knowledge. The goal of the thesis crystallized in the direction of stimulating reflection on the importance and valorization of modernist architecture in Croatia, through the example of the Children's health resort in Krvavica.
