The Spanish Towers: The Stone Sentinels Dominating Porto Zafferano
Navigating along the Teulada coast, your gaze is inevitably captured by solitary cylindrical structures standing atop the most rugged promontories. These are the Spanish Towers, a system of coastal fortifications erected between the 16th and 17th centuries to protect the Kingdom of Sardinia from the devastating raids of Barbary and Saracen pirates.
These “stone sentinels” formed an uninterrupted visual communication network: from a smoke signal at one tower, the alarm would spread across the entire island in minutes, allowing inland populations to reach safety.
The Defense System in Numbers
Historical and architectural details of the fortifications guarding the Porto Zafferano quadrant.
- Construction Period
- Second half of the 16th century (Reign of Philip II of Spain).
- Strategic Function
- Sighting, signaling, and active defense (light artillery).
- Typology
- 'Senzilla' towers (sighting) and 'Gagliarde' towers (heavy defense).
- Iconic Tower
- Torre del Budello (overlooks the entrance to Marina di Teulada).
- Visibility
- Optimal from the sea; many are located within restricted military zones.
Torre del Budello: The Harbor Guardian
Located on a promontory east of Marina di Teulada, the Torre del Budello is one of the best-preserved in the area. Built in 1601, it dominates the access to the stretch of sea leading to Porto Zafferano.
From its privileged position, the tower keepers (torrieri) could scan the horizon toward Capo Teulada and warn the nearby village of Teulada—then located further inland for safety—of any suspicious sails on the horizon. Today, this tower serves as the visual landmark for anyone setting sail toward the military zone.
Historical Trivia
The towers were garrisoned by ‘Alcaides’ (commanders) and soldiers who lived in extremely harsh conditions, often isolated for months, with the vital task of keeping fires lit for night signaling.
Torre di Porto Scudo: Inside the Range
Heading west, within the restricted area of the Military Range, stands the Torre di Porto Scudo. This fortification is particularly significant as it protects one of the most sheltered and strategic coves on the coast.
Being located in a “closed” zone, the tower has remained almost immune to modern vandalism, preserving its austere majesty intact. Seeing it from the sea during an authorized tour offers a unique perspective on the “Delta” defense system, where ancient Aragonese strategy meets modern NATO surveillance.

Architecture and Communication
The towers were not simple bunkers, but sophisticated communication tools.
- Structure: Often divided into two floors, with the entrance located on the first floor (accessible only via retractable ladders) to prevent immediate access by pirates.
- Signals: During the day, they used smoke (fumate); at night, large fires. In case of fog, large horns or bells were used.
Observing these towers from a boat allows one to understand the logic of their builders: each tower had to “see” and “be seen” by at least two neighboring towers.
