The seat of the municipality is the city of Setúbal, located on the northern bank of the Sado river estuary, approximately 40 km south of Portugal's capital, Lisbon. It is also the seat of the district of Setúbal.

In the beginning of the 20th century, Setúbal was an important center of Portugal's fishing industry, sardines in particular. None of the many factories then created are operating today. Although its industrial life is in decline, tourism is perceived as a big opportunity for the future since the nearby coast of the Arrábida natural park offers beautiful beaches and unspoilt nature. A colony of dolphins lives in the Sado River, and across the river from Setúbal lies the peninsula of Tróia, where several high-rise luxury resorts were built and abandoned after the realization they were being constructed on sinking, unstable land. As of 2005, a new luxury resort is planned to replace today's Tróia. One can view Tróia at Albarquel, a beach located in the very beginning of Arrábida.

The main historical monument of the city of Setúbal is the Monastery of Jesus, with a 15th-16th century church that represents one of the first buildings in the Portuguese late Gothic style known as Manueline.

Also of interest are the São Julião Church, also with Manueline portals, and a 16th-17th century fortress (Castelo de São Felipe), now turned into a luxury hotel (pousada).
