Greece - The wider area of Mount Olympus (2026)

Mount Olympus is situated in northern Greece and is the highest mountain in the country. Its microclimate, resulting from its proximity to the sea and abrupt elevation, produces a remarkable diversity in terrain, climate, and vegetation. In this landscape, the ancient Greeks situated the abode of their Twelve Olympian Gods, with Zeus as their sovereign, as well as the Muses and Graces. Through the writings of Hesiod and Homer, Mount Olympus became a central point of reference for Greek mythology throughout the Greek and Roman worlds, rendering Mount Olympus an enduring emblem of Greek civilisation. The property features striking landforms, including glacial cirques, limestone cliffs, karstic sinkholes, and olistolith fields, while sharp ridges like the Mytikas-Stefani complex and deep gorges such as the Enipeas illustrate ongoing neotectonic activity. Mount Olympus has served as a glacial refugium for forest species and is also a Mediterranean plant biodiversity and endemism hotspot.

Denmark - The Bony Fish Fossils of the Western Limfjord – Evolution and Climate Adaptation in the Earliest Eocene (2026)

The serial property, located in the Western Limfjord sea of northern Jutland, Denmark, comprise the coastal cliffs of Hanklit and Knudeklint, which contain some of the world’s best-preserved fossil fishes. The property represents the oldest and most important site for understanding the early evolution and diversification of modern bony fishes (teleosts) following the end-Cretaceous mass extinction. Preserved within diatomite-rich deposits and volcanic ash layers, the exceptional fossil record spans the Paleocene–Eocene Thermal Maximum (PETM) and the subsequent cooling period, providing unique evidence of biotic responses to major climatic change. The property contains abundant and exceptionally well-preserved marine and terrestrial fossils, including fishes, sea turtles, birds, insects, plants, and microfossils, offering an unparalleled insight into the earliest Eocene biosphere. It preserves between 25 and 29 fish orders and more than 80 fish species, documenting the evolution and adaptation of early modern fish lineages during a period of rapid environmental change.

Italy - The system of Italian-style condominio theatres of the 18th and 19th centuries in Central Italy

The serial property comprises ten Italian‑style condominio theatres built between the mid‑18th and late 19th centuries across Emilia‑Romagna, Marche, and Umbria in central Italy. Architecturally representative of Neoclassicism with Late Baroque influences, these theatres feature tiered boxes, carefully designed auditoriums for optimal acoustics and visibility, stalls, foyers, ridotti, and historic stage machinery. They embody the innovative “condominio” system, a model of collective ownership and public‑private financing that enabled municipalities and private citizens to collaborate in constructing theatres in small and medium‑sized towns. This system fostered the growth of a widespread cultural network, providing new representational spaces for the emerging bourgeoisie and broadening public access to the performing arts. Located at the heart of historic town centres, these theatres became important civic meeting places, hosting performances and public events and contributing to the formation of public opinion.

Turkiye - Sardis and the Lydian Tumuli of Bin Tepe (2025)

Sardis was the capital of the Lydians, a powerful Iron Age civilization (8th-6th centuries BCE) known for its wealth and early coinage production. The city had a unique urban structure with fortified walls, terraces, and distinct zones, including settlements, sanctuaries, and cemeteries. The cemetery of Bin Tepe features some of the largest tumulus tombs in the world. The Lydians developed a distinct language and religious system and were widely mentioned in Greek, Roman, and European texts. After their fall, Sardis remained significant under Persian, Greek, Roman, and Byzantine rule.

Italy - Funerary Tradition in the Prehistory of Sardinia – The domus de janas (2025)

"This serial property is an ensemble of  hypogean burials and necropolises located in Sardinia, created between the 5th and 3rd millennia BCE. These sites reflect the daily life and funerary practices of prehistoric Sardinian communities.  The domus de janas, locally known as “fairy houses,” are rock-cut tombs that reflect the funerary practices, spiritual beliefs, and social evolution of Sardinia’s prehistoric communities. These structures feature complex layouts, symbolic decorations, and figurative motifs that testify to the transformation of the relationship between the living and the dead in a society transitioning toward more complex forms of social organization. They  represent the most extensive and rich manifestation of hypogean funerary architecture in the western Mediterranean, exemplifying a phenomenon attested by approximately 3,500 hypogea spread across the entire island."

Denmark - Mons Klint (2025)

"Featuring a dramatic glaciotectonic landscape shaped by Pleistocene glaciers, the property includes chalk cliffs, rolling hills, kame and kettle topography, and outwash plains. Visible cliff cross-sections reveal intense folding and faulting of Cretaceous chalk and Quaternary sediments. The area supports rare habitats like calcareous grasslands and beech forests, hosting diverse flora and fauna, including 18 species of orchid, and the almost-threatened Large Blue butterfly. Erosion continuously exposes fossils and reshapes the cliffs."

Bosnia and Herzegovina - Vjetrenica Cave, Ravno

Located in the Dinaric mountain range, the property stands out with its remarkable cave biodiversity and endemicity. Known since antiquity, the well-conserved representation of karst topography is one of the world’s most important biodiversity hotspots for cave-dwelling fauna, notably subterranean aquatic fauna. It is home to a number of globally threatened vertebrate species, and the only subterranean tubeworm in the world, as well as a diversity of plant species endemic to the Balkans. Additionally, several of the species found in Vjetrenica Cave are tertiary and pre-tertiary relict species, meaning that many of them can be considered living fossils whose closest relatives went extinct a long time ago.

Romania - Frontiers of the Roman Empire - Dacia

"From 500 BCE on, the Roman Empire extended its territory across parts of Europe and North Africa until its frontier totaled some 7,500 kilometres by the 2nd century. The Romanian segment, the Dacian Limes, was operational from 106 to 271 CE. The property comprises 277 component parts and represents the longest, most complex land border of a former Roman province in Europe. Traversing diverse landscapes, it is defined by a network of individual sites that include legionary fortresses, auxiliary forts, earthen ramparts, watch towers, temporary camps and secular buildings. Dacia was the only Roman province entirely north of the Danube River. Its frontier protected it from ‘barbarian’ populations and controlled access to valuable gold and salt resources."

Greece - Zagori Cultural Landscape

Located in a remote rural landscape in northwestern Greece, small stone villages known as Zagorochoria extend along the western slopes of the northern part of the Pindus mountain range. These traditional villages, typically organized around a central square containing a plane tree and surrounded by sacred forests maintained by local communities, showcase a traditional architecture adapted to the mountain topography. A network of stone-arched bridges, stone cobbled paths, and stone staircases linking the villages formed a system that served as a political and social unit connecting the communities of the Voïdomatis River basin.

Turkiye - Wooden Hypostyle Mosques of Medieval Anatolia

This serial property is comprised of five hypostyle mosques built in Anatolia between the late 13th and mid-14th centuries, each located in a different province of present-day Türkiye. The unusual structural system of the mosques combines an exterior building envelope built of masonry with multiple rows of wooden interior columns (“hypostyle”) that support a flat wooden ceiling and the roof. These mosques are known for the skilful woodcarving and handiwork used in their structures, architectural fittings, and furnishings.

Russia - Astronomical Observatories of Kazan Federal University

The property is comprised of two component parts: one in the historical centre of Kazan and the other in a forested suburban area west of the city. The Kazan City Astronomical Observatory, built in 1837, is located on the University campus and the building is characterized by a semi-circular façade and three towers with domes built to house astronomical instruments. The suburban Engelhardt Astronomical Observatory includes structures for sky observations and residential buildings, all located within a park. The observatories have been preserved complete with astronomical instruments and today perform mainly educational functions.

Turkiye - Gordion

"Located in an open rural landscape, the archaeological site of Gordion is a multi-layered ancient settlement, encompassing the remains of the ancient capital of Phrygia, an Iron Age independent kingdom. The key elements of this archaeological site include the Citadel Mound, the Lower Town, the Outer Town and Fortifications, and several burial mounds and tumuli with their surrounding landscape. Archaeological excavations and research have revealed a wealth of remains that document construction techniques, spatial arrangements, defensive structures, and inhumation practices that shed light on Phrygian culture and economy."

Missing - Turkey - Arslantepe Mound

"Arslantepe Mound is a 30-metre-tall archaeological tell located in the Malatya plain, 12 km south-west of the Euphrates River. Archaeological evidence from the site testifies to its occupation from at least the 6th millennium BCE up until the late Roman period. The earliest layers of the Early Uruk period are characterized by adobe houses from the first half of the 4th millennium BCE. The most prominent and flourishing period of the site was in the Late Chalcolithic period, during which the so-called palace complex was constructed. Considerable evidence also testifies to the Early Bronze Age period, most prominently identified by the Royal Tomb complex. The archaeological stratigraphy then extends to the Paleo-Assyrian and Hittite periods, including Neo-Hittite levels. The site illustrates the processes which led to the emergence of a State society in the Near East and a sophisticated bureaucratic system that predates writing. Exceptional metal objects and weapons have been excavated at the site, among them the earliest swords so far known in the world, which suggests the beginning of forms of organized combat as the prerogative of an elite, who exhibited them as instruments of their new political power.
