In 1939 the remains of the nave, as well as a forge and a cow shed were uncovered.
The stone foundations of the house were roofed over to protect against wind and weather in 1957 and can be visited.
Further excavations in 1992–1993 brought to light a church that dates from the same period as the nave.
About 5 km southwest of the excavation site, a reconstruction of the Stöng courtyard and church was built, the Freiljóðveldisbær open-air museum .
Stöng is one of the best preserved medieval buildings in Iceland and is particularly important because it is a rare example of the wooden construction previously practiced in Iceland, which later had to be abandoned due to a lack of building materials.
The excavation of Stöngs under the direction of the Danish archaeologist Aage Roussell was part of a whole series of excavations in the summer of 1939. Five more courtyards and one cemetery were uncovered in Þjórsárdalur and two courtyards in Borgarfjörður in western Iceland .
The Þjórsárdalur archaeological research program was one of the most important in Iceland in the 20th century for several reasons:
- For the first time ever, research was carried out in Iceland by trained archaeologists.
- With the excavations of Þjórsárdalur, the collaboration between Icelandic archaeologists and natural scientists began.
- In connection with the excavations, the geologist Sigurður Þorarinsson developed a new dating method , tephrochronology .
- Pollen analyzes and extensive studies of skeletal relics were carried out.
