A reconstructed chapel of the patron saint of the island of Rab, St Christopher, this church now serves as a museum and a lapidary.
The new permanent exhibition of the Town Lapidarium was opened in 2014, 35 years after the exhibition first opened. The new Town Lapidarium exhibition presents the historical and architectural heritage of the town in a new way. The author of the exhibition, Mr Miljenko Domijan, explains that "the exhibition was renovated and modernised both in terms of technology and the information it provides. The collection now includes new artefacts, especially from early Christian times, such as a stone reliquary from the 4th century. Since this exhibition is the only information about the architectural development of the town, it also includes information boards that explain its history from Antiquity to the present day. Every historical period (Antiquity, Early Christianity, Pre-Romanesque, 11th century, Romanesque, Gothic, Renaissance, Baroque) is illustrated by corresponding architectural monuments, texts and drawings. The introductory informative scheme includes texts and the layout of the town with marked areas that are further explained on individual information boards."
