The Palmeros de Chacao are heirs to a tradition that dates back to around 1770, when the parish priest José Antonio Mohedano, faced with the recurrence of the plague of yellow fever that plagued the valley of Caracas, wanted to ask God for clemency with a promise and sent the workers of the haciendas near the mountain (today El Avila National Park), to look for the royal palm to lower its leaves, evoking the biblical passage of Jesus' entrance to Jerusalem).
