The Prehistoric Megalithic Structures of Ħaġar Qim and Mnajdra, part of the World Heritage site of the ‘Megalithic Temples of Malta’ is managed by Heritage Malta.

Between 2004-2006, Heritage Malta with the financial support of the European Regional Development Funds (ERDF) developed a project to reduce damage caused by deterioration and structural problems of the site.  Among different factors, these archaeological sites were facing issues connected to the continuous exposure weather and salt erosion, dust and pollution, humidity, solar radiation, volcanic emissions, as well as biological organisms.

The project focused on finding long term solutions for both heritage conservation and accessibility by visitors.

The project included the design and construction of shelters for the Ħaġar Qim and Mnajdra Megalithic Structures to assist in the conservation aspect of these sites.  These structures were designed with data collected from monitoring of the sites and their wider setting.
