In the Late Middle Ages and then in the Aragonese period with Paolo and Mariotto Verità, the small town of Mariotto was affected by increasing agricultural development, until King Ferdinand obtained confirmation of the fiefdom and permission to be able to build a house or tower equipped with defenses. The old chapel was built in the late 1800s near the baronial palace (one of the first palaces built in 1450/1500 in the area, later known as the “palace of Barese”) but proved inadequate for the growing population. The Bishop of Ruvo and Bitonto, Don Tommaso De Stefano, had the project drawn up and found in the land donated to him by Luigi Sylos, the site on which to build the new building of the Church Maria SS. Addolorata. The exterior of the church with its bell tower preserves the original structure in Romanesque style. Over time, it has been embellished by the lunette of the facade decorated with majolica tiles, windows with historiated stained glass windows by Olivetan priest Ambrogio Fumagalli, mosaic of the Blessing Christ, Tabernacle, and panel decorating the corner of the baptismal font by architect-painter Father Francesco Radaelli.
