Chiesa di San Gaetano
The church of San Gaetano was founded in the 17th century by the Theatine order, which arrived in Barletta in the early years of the century. When the Theatine order was suppressed by the royal decree of Murat on 7 September 1809, the church came under the jurisdiction of the parish priest of the church of San Giacomo, who in turn entrusted it to the Brothers of the Holy Trinity. The friars brought with them the precious relic of the Holy Thorn, of which they had become the guardians and which they were responsible for solemnising on Passion Sunday. The building was granted to the municipality and used for public offices.
