Restoration of the Birgu Fortifications - ERDF Project
The Birgu fortifications are one of Malta’s four major historical works of military architecture and fortification earmarked for restoration by the Ministry for Resources and Rural Affairs (MRR) as part of the programme of projects co-financed by European Union funds.
This extensive project, the first of its kind to address the island’s rich and unique military architecture heritage, aims to restore and rehabilitate the Birgu bastioned fortifications and ditch and revest them with the dignity that this historical fortress rightfully deserve as Malta’s first bastioned maritime city and one of the prime cultural and tourism assets that the Island has to offer. The projected interventions, which now have been underway since January 2008, designed and implemented by the Restoration Unit within the Works Division, MRRA, are aimed both at the restoration of the ramparts’ consumed physical fabric as well as the recuperation of the overall legibility of Birgu’s fortified enciente, obscured over the years by modern accretions and unsympathetic development. The project also seeks to recuperate many inaccessible areas along the fortified enceinte so as to open them up for public enjoyment.
The four selected projects (Valletta, Birgu, Mdina and the Gozo Citadel) comprise a substantial investment of around 36 million Euros spread over a period of seven years and involve the restoration of some 135,000m2 of rampart elevations over a combined perimeter length of around 6 km. This project is part-financed by the European Union through the European Regional Development Fund under Operation Programme I ‘Investing in Competitiveness for a Better Quality of Life’ for Cohesion Policy 2007-2013, with a co-financing rate of 85% EU Funds (ERDF) and 15% National Funds.”
Birgu - historical context and significance
Giacomo Bosio, the Order’s historian, states that Grand Master L’Isle Adam, immediately upon the Order’s arrival in
Birgu’s crowning moment came in 1565, when it withstood three months of Turkish bombardment and assaults during the Great Siege of Malta by the Ottoman armada sent to capture the island bt Sultan Suleiman, earning, as a result, its title of Vittoriosa (The Victorious One). The city’s defences, which had been pulverized by the incessant Turkish artillery bombardment, were largely rebuilt after the siege under the supervision of the Maltese military engineer Girolmu Cassar.
The construction of the new piazza reale of Valletta immediately after the siege, however, placed a great strain on the Order’s resources so that the upkeep of the Birgu fortifications came to be neglected over the course of the closing decades of the sixteenth century until rumours of a possible Turkish attack in 1633 forced a re-appraisal of its state of repair. Furthermore, the commencement of the massive Sta Margherita enceinte in 1638, followed by the even larger and all-encompassing Cottonera enceinte in 1670, served to relieve Birgu of its front-line pressures and, in the process, robbing it of most of its military value.
By the beginning of the eighteenth century, however, the Order began once again to address the problems of the role and importance of the old fortress which was still considered critical for the defence of the harbour anchorages and naval servicing areas. As a result, there materialized in the early decades of the 1700, an extensive transformation of Birgu into the present day Baroque fortress with ornamental triumphal gateways, and sophisticated outerworks with batteries, countermines, and glacis. Responsible for this military revival and architectural transformation was a small French military mission, headed by Brigadier Rene Jacob de Tigné and his deputy Charles Francois de Mondion, sent by the King of France in answer to the Order’s request for military assistance in 1714 when faced with the threat of a Turkish invasion. Together, these two French military engineers designed and implemented the complete overhaul and renovation of Birgu’s fortifications – the bastions, cavaliers, curtains, outerworks, and gateways. The Post of Castile, in particular, that renowned site of the most important battles of the Great Siege in 1565, received special attention and was reinforced with a new built-in casemated bastioned retrenchment.
Nature and Scope of the Restoration Works
The ERDF restoration project on the Birgu Fortifications set out to achieve the following main objectives
The project is divided into fifteen phases as indicated in the table below:
1. The restoration and repair of the physical fabric.
Birgu has some two kilometers of rampart walls and rock-hewn counterscarp, fashioned out of the beautiful honey-coloured, but nonetheless fragile, Globigerina limestone. Erosion, pollution, vegetation, continual human use (and misuse), as well as insensitive modern accretions (metal pipes, fixtures and cables), have inevitably all taken their toll of the fortifications’ old masonry fabric.
The projected interventions, therefore, are designed to clean and repair all the surfaces of the bastions, curtains, cavaliers, and gates making up the fortified enceinte and replace, where necessary, highly consumed elements in order to arrest the considerable processes of decay that threaten the architectural integrity of this unique historical monument.
The restoration interventions are exceuted to the highest standards and in accordance with established scientific criteria and practices.

2. Recuperation of the legibility of Birgu’s enceinte
Over the course of the past century, some important areas of Birgu’s fortifications have lost their integrity and legibility as a result of short-sighted modern interventions. Some areas were either obstructed with utilitarian buildings and structures, filled in, or simply demolished to make way for roads - all of which have served to detract from the fortification’s full architectural and physical power.
The area known as the Hornworks of the Post of Castile was one such place. This important stretch of the Birgu enceinte, facing Kalkara Creek, and the site of the most important battles of the Great Siege of 1565, provides one of the most dramatic and sculpturally powerful statements of the bastioned trace as introduced by the knights of the Order of
The Project also seeks to unearth the ditch around the counterguard known as the Couvre Porte (filled-in after the Second World War with war-damage debris) and thereby re-establish the linear continuity of the enceinte with the construction of an arch where the wall was crudely interrupted along the face of the Bastion of St John in order to make way for a modern road into the town. (See images below)

An important objective of the Birgu Restoration project is the recuperation of considerable areas of the fortifications which to-date have remained inaccessible to the public. Amongst these are the Bastion of St James and the large tract of ramparts known as the Post of Castile. Between them, these two areas consitute about 25 percent of the Birgu fortifications. The project seeks to take-over these spaces, restore, and rehabilitate them, and open them up for public enjoyment as places of historical, cultural and tourism activities.

5. Introduction of a new lighting system
The project seeks to introduce a co-ordinated, sustainable, and economical lighting system which will provide evening and night-time appreciation of the fortifications of Birgu from the immediate and surrounding locations and other main scenic view points around the Grand Harbour. The lighting project will also include Birgu’s intra-mural and historic urban fabric and architectural heritage. The project will seek to promote an artistic enhancement and experience of the heritage assets, create safe and pleasant outdoor spaces, and highlight and emphasise important features such as the principal Baroque gateways, cavaliers, bastions, embrasures, ditch and facades of historical buildings.

6. Repaving of the historical intra-mural area (collachium)
Birgu was a fortress and, therefore, as a fortified city it served both military and social functions. The city, which originated as a medieval fishermen’s village huddled beneath the shadow of a castle, retained its largely orginal medieval layout of narrow winding streets and alleys. After the coming of the knights in 1530, and the enclosure of the town within a bastioned enceinte, a substantial part of the intra-mural area was reserved exclusively for the knights and their main buildings – conventual church, hospital, auberges, and palaces etc – the so-called Collachio .
Unfortunately, most of the streets and other spaces within the project boundary have, over the passage of time, either lost their original paving or were re-surfaced in asphalt or concrete. The project seeks to restore the paving as an essential component of the historic urban fabric that manages to communicate the ‘spirit of the place’.

7. Project Benefits
The primary aim of the project is to address the problems of restoration and rehabilitation of the decaying architectural fabric of Birgu’s unique and historic system of fortifications with the aim of its revalorization as an integral and focal part of
The significance of the Birgu fortifications restoration project, however, extends far beyond the physical restoration of the architectural features and fabric of the ramparts and bastions. The restoration programme, therefore, will also serve to boost the regeneration of the areas within and around the fortifications, providing an improved quality of life for the inhabitants of the localities.
Indeed, to this end, the project has, from its very inception, found the unstinting support and collaboration of both the Birgu Local Council and the community and people of Birgu.
8. Progress to-date
Restoration works on the Birgu fortifications programme are now well underway. At the time of writing of this report, four tenders have already been awarded, and another two are about to be awarded, while another tender is in the publication stage. Restoration works are currently in progress along the ramparts of St. John Bastion, its adjoining curtain and counterscarp, and on St. John Cavalier, while the Oil-depot building abutting the hornworks of the Post of Castile has now been dismantled. Restoration works are now also set to begin on the Counterguard known as Couvre Porte while a documentation exercise is set to commence on the network of fortifications in the area of the Post of Castile.
