View Luther's Residence, a large cloister that the Reformer Martin Luther used as a home. Visit Wittenberg's Market Square, dominated by the Town Hall and the towers of the City Church. Have a look at the Luther Memorial. Behind the market is an old church called Stadtkirche, where Luther preached and got married to Katharina von Bora. Pass Castle Church, the famous church where Martin Luther nailed his 95 Theses to the door. Luther gave some of his sermons in this church and now is buried just under the pulpit. Another important landmark is Luther's Oak., wherein 1520, Luther's supporters burned a stack of writings of Church doctrine. In 1830, an oak tree was planted on the spot where all this allegedly took place. We finish our tour with Wittenberg University, where you can still see parts of the structure dating back to the XVI century. Luther himself worked within these walls and quotations of his are displayed on the walls in the entrance hall.
