Rethinking Holocene landscape evolution at Olympia (Greece): challenging the palaeolake hypothesis in favour of an open fluvial system
A new geomorphological and sediment-budget analysis challenges the long-held hypothesis of a persistent palaeolake at Olympia, Greece. Instead, evidence from stratigraphic records, microfaunal assemblages, and regional source-to-sink comparisons supports an open fluvial system throughout the Holocene. The study reveals that sediment volumes in the Alpheios delta and floodplain exceed potential lake storage by 14–17 times, while palaeohydrological reconstructions show that presumed harbour sites would have been flooded under a lacustrine scenario. Localised late-Holocene block uplift offers an alternative explanation for previously attributed lake-level fluctuations, indicating the Olympia plain functioned as part of an unimpounded river system, with the Alpheios River likely flowing near the sanctuary's southern margin during Antiquity.
Food in Sanctuaries: Markets and Consumption
Archaeological evidence at the Sanctuary of Olympia reveals that large-scale gatherings during panhellenic festivals, such as the Olympic Games, transformed sanctuary areas into open-air tent camps. These camps, often near natural water sources like the Kladeos River, accommodated visitors—including athletes and spectators—who traveled from across Greece and beyond for multi-day events. The discovery of iron support holes for tents, coupled with historical accounts, underscores the logistical challenges and communal nature of these festivals, which attracted tens of thousands of people annually since at least 472 BCE.
On the history of Olympia during the transitional period of the Byzantine era
A reappraisal of pottery and buckle data from the early Byzantine settlement at Olympia suggests that the site was not abandoned as previously thought in the early 7th century, but likely persisted into the late 7th century or beyond. This challenges the long-held belief that Slavic penetration led to the immediate abandonment of the area. The study compares documented pottery types with recently published material from other sites and introduces unpublished buckle data, indicating a possible coexistence of indigenous populations with Slavic newcomers during this transitional period.
The Evolution of Visiting Olympia: From Ancient Pilgrims to the Threshold of Modern Tourism (ca. 1900)
Olympia's transformation into a modern tourist destination was shaped by centuries of cultural, archaeological, and mobility developments. The study reveals that while ancient Olympia served as a proto-touristic center for pilgrimage and athletic events, its revival in the 19th century—driven by philhellenism, Grand Tour trends, and early excavations—laid the foundation for organized tourism. Key factors included standardized guidebooks, archaeological scholarship, national antiquities legislation, and expanding media networks, which collectively integrated Olympia into international tourist circuits by the 1890s. Improved transport links, the first museum, and the Olympic revival further cemented its status as a heritage site, with visitor growth in the early 21st century reflecting this historical evolution.
The Lake of Olympia: Sedimentary evidence of a mid- to late Holocene lake environment in the vicinity of ancient Olympia (western Peloponnese, Greece)
Ancient Olympia, renowned as the site of the Panhellenic Games, was once situated at the shore of a mid-to-late Holocene lake that persisted from the 8th millennium BC until the 6th century AD. This discovery, based on sediment cores and multi-proxy analyses from the Basin of Makrisia and the adjacent Basin of Ladiko, reveals distinct phases of limnic conditions, including freshwater to eutrophic environments. Radiocarbon dating indicates the lake's existence during Olympia's peak cult period, with its disappearance linked to a significant drop in the Alpheios River's water level between the 13th and 14th centuries AD, forming the Olympia Terrace. The study also highlights the lake's impact on river discharge and sediment transport, along with its historical, archaeological, and geomorphological implications.
Connecting Communities in Archaic Greece: Exploring Economic and Political Networks through Data Modelling
Archaeological research at Olympia reveals that economic and political networks in Archaic Greece were more interconnected than previously thought, driven by lucrative trade routes and cultural exchanges.

Inscribed Classical Victory Offerings at Olympia in the longue durée
Victory offerings at the Archaeological Site of Olympia serve as enduring symbols of military triumph, fulfilling dual roles: thanking deities for victory and commemorating the glory of victorious cities. These monuments, prominently featured in Olympia's sanctuary, act as 'lieux de mémoire,' preserving collective memory across centuries. Recent scholarship highlights their memorial significance, particularly from the Persian Wars, with a shift towards analyzing these offerings thematically rather than by date or artist. The study draws on Pau s anias' descriptions and modern art-historical perspectives to explore how these monuments structure narratives of space and time, paralleling ancient Greek practices with Roman mnemonic techniques. This research contributes to understanding the materiality and cultural impact of inscribed victory offerings in antiquity.
The Crown Games of Ancient Greece: Archaeology, Athletes, and Heroes
The Panhellenic Games, including the Olympics, Pythian, Isthmian, and Nemean Games, served as a unifying cultural touchstone for ancient Greek city-states. David Lunt's work highlights their significance in fostering Panhellenism, though it notably excludes later Hellenistic and Roman periods, which saw expanded participation and institutionalization of these games. The study combines archaeological evidence with literary sources to argue that the Games' decline in late antiquity was due to broader societal changes rather than religious conversion or imperial decrees. Additionally, it challenges traditional notions of Greek exclusivity, suggesting that competition itself helped construct a 'Greek' identity. This book offers a valuable introduction to ancient Greek sport and culture, integrating recent scholarship on the topic.
De druk van te hoge verwachtingen
Continuous archaeological research and restoration at the UNESCO World Heritage Site of Olympia have revealed a material reality that differs significantly from early expectations, particularly regarding ancient sculpture.

These interventions, conducted by teams comprising archaeologists, architects, engineers, conservators, and stone-masons, prioritize the preservation of original structural systems while leveraging collective expertise to develop effective methods applicable to a broader range of historical sites. The study highlights two key principles underlying these projects: the collaborative, multi-disciplinary approach and the commitment to maintaining the integrity of the monuments' original designs.
The Columns of the Heraion at Olympia: Dörpfeld and Early Doric Architecture
A groundbreaking re-evaluation of the Temple of Hera at Olympia challenges long-held assumptions about Doric architecture. Contrary to the traditional belief that its columns were initially wooden and later replaced with stone, archaeological evidence, historical testimony from Pausanias, and recent fieldwork suggest the peristyle was likely constructed with stone from the outset. This finding undermines the 'tectonic theory' of Doric origins, which posits a progression from wood to stone in temple construction. The study integrates comparative site analysis and textual sources to reshape our understanding of early Doric architectural development.
Cultural Tourism in Greece at a Time of Economic Crisis
A significant decline in visitor numbers to Greek archaeological sites and museums, including the Acropolis Museum and the National Archaeological Museum, was observed during the economic crisis. Despite the opening of the New Acropolis Museum in 2009 attracting over a million visitors initially, numbers dropped by 7.1% from 2009 to 2010. The study highlights that while museum visits stabilized between 2008 and 2012, overall visitor numbers decreased significantly compared to pre-crisis levels. The economic downturn also exacerbated illegal looting, with substantial seizures of antiquities reported, while restoration efforts on the Athenian Acropolis improved visitor experiences. The research underscores the impact of economic crises on cultural tourism, archaeological fieldwork, and the preservation of heritage sites.
Olympia’s Harbour Site Pheia (Elis, Western Peloponnese, Greece) Destroyed by Tsunami Impact
Research at the UNESCO World Heritage Site of Olympia, Greece, reveals that its harbour site Pheia was destroyed by tsunami impacts, likely in the 6th century AD. The study identified three distinct tsunami events—dating to the 6th millennium BC, around 4300 ± 200 cal BC, and the Byzantine to post-Byzantine period—using sedimentological, geoarchaeological, and geochemical analyses of marine deposits found far inland. These deposits, some cemented into beachrock, suggest tsunamis reached up to 18–20 meters above current sea level due to wave refraction and channeling effects, such as the Katakolo Pass. The findings highlight the significant tsunami risk posed by the seismically active Hellenic Arc, where tectonic plate subduction generates destructive waves along the Greek coast.
Media framing of a cultural disaster: the case of Ancient Olympia
National media coverage of the 2007 forest fires at Ancient Olympia, a UNESCO World Heritage Site and cradle of the Olympic Games, primarily focused on the disaster itself rather than the site's cultural significance or the museums' response. A study analyzing framing choices in Greek newspapers found minimal representation of museum activities during the crisis, highlighting a need for improved media relations strategies to better communicate the site's unique heritage value amid natural disasters.
