The ruins of the Church of Santa Maria del Buon Consiglio in Bari offer a glimpse into the city's history. Originally a Byzantine church dating back to the 9th and 10th centuries, the site was mistakenly demolished in the 1930s but still retains its columns and mosaic flooring. Legend has it that the church was built after a dispute between locals and Byzantines ended in a truce, hence the name "Our Lady of Good Counsel." On-site, there isn't any plaque sharing more information and details about the church, but I still think this hidden gem is worth seeing.
