GRAVEN AAN DE RAND VAN GRONINGEN (GR.)
In 1991 three major excavations in various ways revealed the boundaries of Groningen in different periods. Beneath the former Rode Weeshuis orphanage postholes of a 5th/6th century house and a well were excavated. North of this house, ploughmarks were found, possibly dating from the same period. They probably form the northern limit of pre-medieval Groningen. At the Schoolholm were found the remains of wooden houses from the 11th/12th century, built on the eastern bank of the Drentse A. Beneath the former Zuiderkerkhof cemetery, and just outside the 12th-century town wall and moat, parts of houses (c. 11th/12th century) and fields (11th/12th until c. 17th century) were excavated.
