What is a Moravian star?
A Moravian star (German: Herrnhuter Stern) is an illuminated piece of Advent or Christmas decoration popular in Germany and in places in America and Europe where there are Moravian congregations. The stars take their English name from the Moravian Church; in Germany, they are known as Herrnhut stars, named for the Moravian Mother Community in Saxony, Germany, where they were first commercially produced.
