The Serbs of Split received their Orthodox parish in April 1922. The Orthodox Municipality was founded and for that they were again given the land on which to build the church, located on Queen Mary's Way. The land on Queen Mary's Way did not suit Serbs. In return, they were given new land. In 1925, she replaced the space on Obrov with 50,000 acreage for the SOC on the move from the Old Place to the present Catholic-Theological Faculty, practically the entire complex of the former monastery of St. Mary, or the barracks. By 1933, the number of Orthodox in Split had increased by immigration to 2000, from those 3 Orthodox families in 1890. In 1933, the Serbian Orthodox Church was granted the assembly, which wanted to erect a monumentally large church of St. Sava that was to be erected on the site of the demolished Catholic monastery and surrounding buildings. The designs were provided by architect Alexander Deroko (Assistant Professor at Belgrade Technical Faculty). In September 1935, the old Catholic church and part of the monastery building were demolished. Then they found a fragment of a pilaster with a cross and an inscription, as well as a part of the gable of the altar partition with an inscription on which St. Benedict. One of the first findings is in the Archaeological Museum in Split today, and the other is in the Museum of Croatian Archaeological Monuments. Construction work continued and more fragments were found. In 1937, the Tutoring of the Serbian Orthodox Church donated the finds to the Archaeological Museum. Some of the found elements date back to the 11th century and the ancient Croatian era (knitting ornamentation), and some are from Roman times: ancient stelae, fragments of sarcophagi, elements with Greek and Roman inscriptions, cannulated pilasters, cornices, pilonics, Romanesque capitals, columns, and there were also baroque frames.Construction work on the construction of the Serbian church was interrupted in 1941. Until now, they have built walls and columns 8 meters high, from the planned 28 meters plus a roof with a dome and a cross. The originally planned style was a non-Byzantine style.
