The authors analyse the archival sources regarding the history of the building located in Kobler Square in Rijeka, which was used as a town hall from the 16th to 19th centuries. It was originally built as a residential house and then repurposed for town hall in 1532. Over the course of the centuries, it underwent numerous changes. The most significant one was undertaken from 1740 to 1745 by architect Antonio Verneda, who had the second floor added, adjoined the neighbouring house, and redesigned the facades in the baroque style. The building was damaged in the earthquake of 1750, after which it was restored several times. In the late 18th century, some of its rooms were used for different social and public events. In 1833, the city council moved out to the former Augustine monastery, and the building was converted to stores and apartments. Being located on the intersection of main streets and the central square, Rijeka's Old Town Hall has urbanistic relevance. The paper also discusses the results of conservation research conducted on the building, which enabled distinguishing of the construction phases.
