The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Malta ratified the convention on 14 November 1978, making its sites eligible for inclusion on the list.
Sites in Malta were first inscribed on the list at the 4th Session of the World Heritage Committee, held in Paris, France, in 1980. At that session, all three current sites were added to the list: the Ħal Saflieni Hypogeum, City of Valletta, and Ġgantija Temples. In 1992, the temples of Ħaġar Qim, Mnajdra, Ta' Ħaġrat, Skorba, and Tarxien were added to the site of Ġgantija Temples, to form the Megalithic Temples of Malta site. Further minor modification of boundaries of this site took place in 2015. All three sites are listed as cultural sites, as determined by the organization's selection criteria.
|Site||Image||Location||Year listed||UNESCO data||Description|
|Ħal Saflieni Hypogeum||Paola||1980||130; iii (cultural)||The hypogeum is a large subterranean structure that was used as an underground cemetery between 4000 BC and 2500 BC and was discovered in 1902. Three superimposed levels of chambers were carved into soft globigerina limestone, with some chambers imitating the architecture of the contemporary above-ground megalithic temples. The hypogeum initially contained the remains of about 7000 individuals. The excavations provided insight into neolithic burial rituals, which likely had several stages. Pottery vessels and stone and clay amulets were recovered from the site, as well as stone and clay human figures, including a famous statue depicting a woman lying on a bed or couch, called The Sleeping Lady.|
|City of Valletta||Valletta||1980||131; i, vi (cultural)||The city of Valletta was founded in 1566. The Knights of St John conceived and planned the city as a single, holistic creation of the late Renaissance, with a uniform grid plan within fortified city walls. Although experiencing renovations and an extensive damage during World War II, a high proportion of the urban fabric has been preserved or restored. Some of the Valletta's 320 monuments include Saint John's Co-Cathedral, the Grandmaster's Palace, the Auberge de Castille, the Auberge de Provence, the Auberge d'Italie, the Auberge d'Aragon, and the churches of Our Lady of Victory, St. Catherine and il Gesù, as well as the 18th century constructions such as the Auberge de Bavière, the Church of the Shipwreck of St Paul, and the Manoel Theatre.|
|Megalithic Temples of Malta||Xagħra, Qrendi, Mġarr, and Tarxien||1980||132; iv (cultural)||The site contains seven prehistoric temples at six sites (originally, the site only listed the two Ġgantija temples and was extended in 1992) that were constructed during the 4th and 3rd millennium BC. These temples are among oldest stone free-standing structures in the world and likely had important ritual significance for a highly organized society. Although each temple is different in architectural design, they usually contain an elliptical forecourt in front of a concave façade. The surviving horizontal masonry courses indicate that the monuments had corbelled roofs, which was a remarkably sophisticated solution for its time. Decorative features of the temples include panels with drilled holes and bas-relief panels depicting spiral motifs, trees, plants and various animals.|
In addition to the sites inscribed on the World Heritage list, member states can maintain a list of tentative sites that they may consider for nomination. Nominations for the World Heritage list are only accepted if the site has previously been listed on the tentative list. As of 2018, Malta had seven such sites on its tentative list, all of which were added in 1998.

By 1907, the fortifications had lost their military significance and were abandoned.|
