Career
Adam appears to have been of Westphalian origin and probably came from the city of Düren, alluded to in the byname. He was first active at the building of the choir of Linköping Cathedral (about 1487-1498), and has been identified as one of two masons whose style is clearly recognisable in the ornaments there. He was probably the architect of the fortified house of Glimmingehus.
He later restored the crypt of Lund cathedral, where he, among other things, installed drain pipes under the floor to prevent flooding.
He was briefly active in Stockholm in 1520-1521, where he built a chapel in the south-eastern part of the Church of Saint Nicolas (Storkyrkan), where he also added an inscribed relief on a pillar, depicting an eel and two lions.
