From Past Horizons:
During evaluation of land prior to the construction of a new hospital in Aalborg, Northern Denmark, archaeologists uncovered an Iron Age village dating back around 2000 years. The settlement differs from other sites of this period because of its well preserved condition, including a number of houses complete with fireplaces, chalk floors and cobbled paving. … A surprise discovery was the skeletal remains of a cat – which has caused some excitement – as this domestic variety was first introduced to Denmark from the Roman Empire during the Iron Age – making this a very early example. Previously, the earliest known domestic cat came from a cremation grave in Kastrup, Jutland dating to c. AD 200.
