History of the Hattusa Excavations
Hattusa (Boğazköy) is the Hittite capital in the Boğazkale district of Çorum, and its excavations span more than a century. This page lists the stages of the work and the excavation directors as the sources state them; where sources differ, both versions are given. For the city itself see Hattuşaş, and for the finds see the Boğazköy Museum.
Early exploration: 1834-1905
According to the Çorum Provincial Directorate of Culture and Tourism, Hattusa was introduced to the scholarly world in 1834 by the Frenchman Charles Texier. The entry in the Türkiye Tourism Encyclopedia says Texier was sent to Anatolia in 1833 and found the ruins near Boğazköy on 28 July. Texier published his drawings in 1839 and suggested the site might be Pteria, while some scholars held that it was the ancient city of Tavium (Atila, 2026).
Later visitors mentioned in the sources include:
- Mordtmann and Barth: the first soundings at Yazılıkaya. Atila (2026) dates them to 1855, the Tourism Encyclopedia to 1858.
- 1861: Georges Perrot, Edmond Guillaume and Jules Delbet photographed Boğazköy, Yazılıkaya and Alacahöyük.
- 1882: Karl Humann drew a plan of the city and took plaster casts of the Yazılıkaya reliefs, which were sent to Berlin.
- 1893-1894: Ernest Chantre made soundings and found fragments of cuneiform tablets at the Great Temple and Büyükkale. Atila (2026) records, in the Ottoman archives, Chantre’s permit application of 9 May 1893.
As the first person to say the site could be the Hittite capital, the Tourism Encyclopedia names Perrot in 1886, whereas the Hittite Monuments website names Archibald Sayce and William Wright in the 1880s.
The first excavation: Winckler and Makridi, 1906-1912
Hugo Winckler asked the Ottoman authorities for a research permit in 1905; the excavation began in 1906 on behalf of the Imperial Museum under Theodor Makridi, with Winckler taking part as the cuneiform specialist. In July 1906 the team worked at Büyükkale, the Great Temple, Temple 5, the Lion Gate and south of the King’s Gate; Atila (2026) writes that about 2,500 tablets and fragments were recovered. Among them was a tablet bearing the Akkadian version of the treaty between the Egyptian king Ramesses II and Hattusili III (see Boğazköy cuneiform tablets).
In 1907 architects, draughtsmen and photographers joined the team; Heinrich Kohl drew the city’s first topographic plan in a few weeks, while Otto Puchstein studied the excavation area. Winckler had the dig house built in 45 days that year. Work continued in the 1911-1912 season; according to the Tourism Encyclopedia, the outbreak of the Balkan War in October 1912, Winckler’s death in April 1913 and the start of the First World War interrupted the dig. More than ten thousand tablets and fragments from this period were taken to Istanbul; Karasu (1995) puts the first excavations’ yield at about 10,400 tablets and fragments. Bedrich Hrozný announced in 1915 that he could read the Hittite texts.
The German Archaeological Institute era: 1931 to the present
Excavation resumed in 1931 on behalf of the German Archaeological Institute under Kurt Bittel. The Tourism Encyclopedia records 3,740 tablet fragments found in 1931-1933, says that from 1934 the tablets were cleaned and copied on site before being handed to the Ankara Museum, and that in 1936 a group of 280 seal impressions came to light (see Hittite seals). The Second World War halted the work again in September 1939; the Çorum Provincial Directorate of Culture and Tourism says work resumed in 1952.

Recent work
Between 2003 and 2005 a small section of the city wall was rebuilt with original methods and materials (Hittite Monuments). The multinational team under Schachner belongs to the Istanbul Department of the German Archaeological Institute. In 2022 Anatolian hieroglyphs written in paint on stone blocks were noticed in the Yerkapı postern; see Yerkapı and the Sphinx Gate. The site was inscribed on the World Heritage List in 1986: Hattusa as a UNESCO World Heritage Site.
The 2026 season
According to an Anadolu Agency (AA) report of 8 August 2026, the 2026 season, the 120th year of the excavations, was carried out by the German Archaeological Institute within the Ministry of Culture and Tourism’s Geleceğe Miras (Heritage for the Future) project. Excavation director Andreas Schachner told AA that this year 55 scientists and students in archaeology, geology, geomorphology, architecture, philology and archaeozoology from Türkiye, Germany, Italy, Hungary and the United States took part, together with 105 workers from the local community, and that excavations were under way at 5 separate points in Hattusa. Milliyet’s report of 10 August 2026 gives the same countries and the same figure of 55 scientists.
According to an AA report of 11 August 2026, at one of these points, the North-western Slope, a well-preserved stone cist grave enclosed by a stone wall was opened in a cemetery of the Early Hellenistic and Galatian period (see Early Hellenistic and Galatian graves at Hattusa). In September 2026 the Ministry of Culture and Tourism announced that a cuneiform tablet fragment found in the excavations at Büyükkale and studied for about a year belonged to a copy of the Kadesh Treaty (Arkeofili; see New Kadesh Treaty tablet fragment).
The 120th year of the excavations was also marked by an exhibition. For the 40th anniversary of Hattusa’s inscription on the UNESCO World Heritage List, Hitit University’s Faculty of Humanities and Social Sciences opened the photography exhibition “Hattuşa Kazılarının 120 Yıllık Görsel Hafızası: 1906-2026” (The 120-Year Visual Memory of the Hattusa Excavations: 1906-2026) at a shopping centre in Çorum in April 2026. It showed 60 photographs selected from the archives of the German Archaeological Institute in Istanbul and the Boğazköy-Hattusa excavation directorate and was open for four days (AA; Arkeolojik Haber).
