This thesis concerns itself with the Church of Our Lady of Mount Carmel, in Trpanj, Croatia. Geographical, legal, and artistic aspects of its history shall be thoroughly described, as well as its appearance, both within and without. Furthermore, this study presents a groundplan of the church and a number of photographs, to aid in understanding the church's many architectural changes through history. It was originally built in the latter half of the 17th century, due to the last will and testament of one Stjepan Gundulić, wherein he stipulated the construction of a church matching in measures the Holy House (Santa Casa) of Loreto. Some information on the church's history was available in scientific literature, but many matters remained unresolved. This thesis offers several new theories, based on practical observation and scientific investigation, as well as exploring familiar knowledge on confraternities and iconography related to the worship of Our Lady of Carmel. The main altar is described in full, as well as its altarpiece, painted by Franjo Kaer of Makarska. Some portraits on these paintings are identified as copies of 18th century lithographs by Marco Pitteri of Venice. The church's sole bye-altar is described too, and authorship is is proposed for the ceiling decorations, apparently the work of a certain Frano Ferenca. In addition to this, authorship is firmly resolved for the old clock situated in the church's belfry; for it is most certainly the work of an Italian clockmaking company called »the brothers Solari«. A new theory is also proposed to explain some windows and doors that were covered up during reconstructions, bringing up the connexion between this church and its inspiration, the Santa Casa of Loreto.
