The exhibition space is situated in the covered western wing of the palace with arcades that open into the gardens. Access is through the yard. Stone monuments, reliefs, sculptures, epitaphs and inscriptions dating from Antiquity to the 20th century are on display behind a barred fence. The area in front of the wing features an Early Christian sarcophagus from the Pul Vele Crikve site, next to the Church of the Assumption of Mary in the heart of the city. Thirteen stone sculptures, portraits of Rijeka citizens, are on display in the north-western part of the gardens. They were commissioned by Rijeka entrepreneur Šimun Adamić at the end of the 18th century, and they represent the witnesses whose testimony led to his conviction and imprisonment. It was later determined that they delivered false testimony. The sculptures were originally installed in front of the Adamić house on the banks of the Rječina River.
