AOC Archaeology Group was commissioned by ARPL Architects to undertake a programme of detailed recording and dendrochronological sampling of joists on the first floor of the medieval John Knox House on the Royal Mile, Edinburgh. The joists have suffered from wet rot, and repairs are required to make them safe. The dendrochronological analysis has resulted in the calendrical dating of two of the joists which suggests that the source of the timber used came from southern Norway. One of the joists was felled in 1559 AD. Previous dendrochronological work on a lintel within the house produced a felling date of 1560 AD and so it is possible that the lintel and the joists were part of the same phase of renovation in 1560 AD or soon after.
