Archaeological discoveries at Korsholm Castle reveal artifacts from 15th century in Finland

Archaeological excavations at Korsholm Castle, which began this week, have yielded significant discoveries. Archaeologist Jan Fast, who is leading the excavations for the third consecutive summer, reports that artifacts from various centuries have already been unearthed. In recent years, most finds have dated back to the 17th century, but this summer’s deeper digging has revealed items from the 15th century. “On just the third day, we made a noteworthy coin discovery. We are approaching the time when the castle was established,” Fast explains.

Last summer’s excavations uncovered a wooden structure dated to the mid-14th century via radiocarbon dating at Uppsala University. Four other samples sent for analysis last year were traced back to the period of 1450-1650, coinciding with the construction of the royal manor by King Gustav Vasa. The first mention of Korsholm Castle is found in the testament of Bo Joninpoika in 1384.

This year, around 70 participants are involved in the digs, including students from Vaasa Lyceum and Vasa Gymnasium, as well as adult learners from Alma College and members of historical societies. “The course at Alma sold out within an hour,” notes Fast. Students Hilma Myllymäki and Atte Koljonen express enthusiasm for their involvement, having already discovered numerous bones, bricks, a coin, and parts of a doll.

Fanny Fagerholm, a bone researcher from Uppsala University, is participating in the excavations for the second time. “We’ve found an incredible number of bones here in good condition, which is rare in Finland,” she comments. The excavations will continue for several more days, with hopes of uncovering more significant artifacts and insights into the region’s history. Fast anticipates continuing the research next year, possibly expanding it into a Nordic excavation week.
