The Four Holy Martyrs is a church located in Agia Galini. It is a 20th century temple built next to an ancient temple that was probably dedicated to the goddess Athena.

The names of the four Martyrs were Angelis, George, Manuel and Nicholas and came from the nearby village of Melambes. In 1821 during the Greek Revolution they were captured and tortured, while on 28 October 1824 they were executed and became Saints.
