El Centellazo Historical milestone · Villamayor, La Armuña, Salamanca Image of Villamayor, not of the place itself. On 1 August 1774 a lightning bolt entered through the bell tower of the church of San Miguel Arcángel seeking earth, without causing casualties. The event was recorded in a slate inscription that the village preserves and that calls the episode the Centellazo. 1 de agosto de 1774 Photo: José Antonio Gil Martínez from Vigo, Spain (CC BY 2.0) What to see and do in Villamayor
