Sada boasts a rich history that dates back to ancient times, with significant influences from Roman, medieval, and maritime cultures. Like many parts of Galicia, Sada was shaped by the Roman Empire, and remnants of this period can still be found in the region. In the Middle Ages, the town flourished as a fishing village, and its maritime heritage continues to play a key role in the local culture today.
Culturally, Sada is deeply connected to traditional Galician customs, including the celebration of its patron saints and local festivals. One of the most significant festivals is the Fiesta del Carmen, which takes place in July and honors the Virgin of Carmen, the protector of fishermen. The festival includes boat parades, music, dancing, and fireworks, drawing visitors from all over the region. Another popular event is the Feria Medieval, where the town transforms into a medieval village, with stalls, performances, and reenactments.
The Galician language is widely spoken here, and the town maintains its traditional architecture and customs. Sada also embraces modern culture, with a variety of local art exhibits, music festivals, and cultural events happening throughout the year.
