In the best case, radiocarbon measurements allow artificial objects to be dated with a precision of 10 calendar years when conventional wiggle-matching onto IntCal09 calibration curve is applied. More precise dating can only achieved by using annually resolved 14 C data, particularly in timespans there are rapid changes atmospheric concentration. The recently observed jump concentration 1.5% between AD 774 and 775, though expected rare, good example for such change. We demonstrate that possible precisely date cutting year timber historically important well-preserved Holy Cross chapel convent St. John Baptist Val Müstair, Switzerland.
