"Intervening as little as possible so as not to alter this heritage asset"

What was the state of the Rambla Tower before the work began?

The outer walls were severely damaged, with eroded sandstone and loosened ashlars and stonework. On the ground floor, parts of the vault and a significant portion of the interior edges had been lost; the weathering process was progressing rapidly and compromised the stability of the structure.

What were the potential risks if action was not taken quickly?

As well as the safety hazard posed by falling material, the property was at risk of permanently losing some of its original elements. In this kind of process, when deterioration is rapid, each windstorm and all saltwater exposure only worsen the damage and reduces the chances of successful conservation.

The project keeps the tower in a ‘state of semi-ruin’. Why this option and not a complete reconstruction?

Because the tower still holds valuable original elements and the priority was to preserve its authenticity. The structure was reinforced without restoring its entire original volume: the aim was for the property to remain as it has come down to us, so as not to add parts whose original placement could not be proven with certainty.

How was this historical respect balanced with structural safety?

The vertical chains of sandstone ashlars—the ‘skeleton’—were reinforced and, instead of rebuilding the entire infill with stone, compatible lime mortar was used to ensure consistency. This stabilises the structure using minimal intervention, ensuring readability and reversibility wherever possible, in line with applicable regulations and international conservation guidelines.

What materials and techniques were used and with what criteria?

The starting point was the study and analysis of mortars to ensure compatibility with the supporting stone. Whenever possible, the original stone that had fallen beside the tower was reused; when not, ashlars made of sandstone with characteristics as close as possible to the originals were selected. Added parts were clearly distinguished from the pre-existing ones to ensure an accurate historical reading.

How much of the original material could be reused?

Much of the material loosened around the tower was reinstated, especially in areas where its placement could be determined with certainty. Where required, parts were replaced with new ones made of sandstone, prioritising compatibility and structural performance.

What were the main technical or logistical challenges of the project?

Accessibility: the site is located on a rocky coastline at a steep incline, within the Natural Park along the publicly owned shoreline. Road transport was unfeasible and the sea route was complicated, so helicopters had to be used to move materials and equipment safely, with minimal disruption.

The tower suffers from a very aggressive coastal climate. What measures ensure durability?

Lime coatings and mortars carefully formulated on the basis of testing were used, mixed with suitable aggregates to resist humidity and salinity. The solution is consistent with the original masonry and supports long-term maintenance: the key is material compatibility, breathability and regular checks for minor refinements.

What does this reinforcement add to Menorca’s heritage?

It situates the tower within a wider context: it’s part of a network of eleven British towers (1798-1802) that were central to the defence of vulnerable points along the coast. Preserving its authenticity provides a better understanding of the British legacy and Menorca’s uniqueness, and adds a heritage landmark to a protected landscape.

How does it fit into the culture and tourism opportunities in the municipality?

Its location in the S'Albufera des Grau Natural Park, next to the Camí de Cavalls route, means it can enrich hiking routes that mix landscape and heritage. The tower, stabilised and readable, is now an accessible interpretation resource for locals and visitors who walk along Maó's coastline.

How is the tower expected to be used and understood by the public?

No indoor use is expected: its value comes from its scenic and educational potential. Information panels explaining the historical context, defensive purpose and arrangement of indoor spaces have already been put up, with 3D photographic models to help visitors visualise the site.

To conclude, what message would you like to give to those who visit the Rambla Tower?

They should see the tower as part of a unique ensemble in the Mediterranean, and as a witness to different layers of history. Preserving it ‘as is’ allows us not only to enjoy the scenery, but also to learn why this legacy is indispensable for Menorca.
