The club was founded in 1938 – apparently receiving some acknowledgement from the then British Mandatory – by way of the British Embassy in Chile – at the time. It is one of the more prestigious clubs in Chile
This is called Dabke de Beit Sahour. Beit Sahour is one of the 4 Christian towns (Bethlehem, Beit Shahour, Beit Jala, and Beit Safafa (now annexed into Jerusalem)) from which many of the Christian Palestinian in Chile are descended.
