The main aim of this ERDF project was to reduce the irreversible damage caused by deterioration and structural problems that the temples were facing due to their continual exposure to the elements. Rain, sea salt spray and dust, fluctuations in temperature and relative humidity, solar radiation, sulphur oxide and nitrous oxide pollution and volcanic emissions, as well as biological organisms, were some of those elements from which these precious Megalithic structures needed long-term protection.
The project included the construction of a Visitors’ Centre, improved accessibility and interpretation measures consisting of nature trails and interpretation facilities. The most important aspect of this project was the design and construction of shelters for the Ħaġar Qim and Mnajdra temples to assist in the conservation aspect of these sites.
Today, the result of this ERDF project is a dramatic reduction in the progressive deterioration of these World Heritage monuments by natural agents. Additionally, the project made it possible to improve further the visitor’s experience, through protection of the temples from sun and rain as well as improvements in the quality of the diffused light below the shelters and improved acoustics.
