Happy Reformation Day (x500)!

Traditionally, October 31 is thought to be the date in 1517 that Martin Luther nailed the 95 theses to the door of All Saints' Church in Wittenberg, Germany. The church still stands, and the door is still there, although it is not easily accessed. When we visited Wittenberg a few months back as part of the "Luther 500" celebration, we were housed very near the church, now called Castle Church. And I took this picture of church history's most important door.

The door. The actual door.
