Church of the Holy Trinity, Split

Church of Holy Trinity (Croatian: Crkva sv. Trojstva) is a Pre-Romanesque style Roman Catholic church located in Split, Croatia. Out of all early-medieval (old Croatian) architectural monuments in Dalmatia, which historians date back to the period between 8th and 11th century, Church of Holy Trinity, with its original shape and rich findings, has a very important place. This small central edifice with six-leaf structure of semicircular arches strung around irregular circle has become one of the most precious heritage monuments of Split and Dalmatia. Church of the Holy Trinity has been added to the register of the most valuable Croatian Cultural Heritage, of the highest category. The church is still in active use with Holy Mass being celebrated every Sunday at 8:30 am, except in the summertime (from June 13 to September 1).
