The church was built on the site of a smaller, older church dedicated to the same saint that dated back to 1753.
The facade's mosaic decorations feature gold leaf, a technique specialized by the Salviati workshop in Murano.
The large central dome is flanked by four smaller domes, echoing the traditional five-domed Byzantine architectural plan.
The iconostasis is composed of 14 large icons set in a rich silver frame, featuring works by the Russian artist Mikhail Shemyakin.
The interior layout is a Greek cross, which is a departure from the traditional rectangular basilican plans found in many neighboring Roman Catholic churches in Trieste.
The church was commissioned by the wealthy Serbian merchant community of Trieste, whose trade connections extended from the Balkans to Vienna.
The Chiesa di San Spiridione is a prominent Serbian Orthodox church in Trieste, constructed between 1861 and 1885 to replace an earlier 18th-century structure. Designed by architect Carlo Maciachini, the building features an elaborate Byzantine-revival style characterized by its prominent central dome and four smaller secondary domes. Its exterior is decorated with intricate polychrome brickwork and distinct majolica tile mosaics created by Salviati of Venice. The interior contains a significant collection of icons, many of which were crafted by Russian and Italian artists in the 19th century. Silver ornaments decorating the iconostasis were produced by masters from Vienna and Trieste, reflecting the city’s historical role as a commercial hub for the Serbian community. The church serves as the primary spiritual center for the Serbian Orthodox community in Trieste. It is situated in the historic Borgo Teresiano district, a neighborhood developed during the 18th-century urban expansion of the city.
