What is striking is that the church is not in the village, but outside it. It is an outstanding piece of medieval architecture. The frescoes covering the interior walls are breathtaking. The north wall depicts the Passion of Jesus; the south wall shows scenes from the life of St Peter. The Last Judgement with the Judge of the World and the Dragon of Hell is depicted on the west side; in the choir you can see the wise and the foolish virgins. Unfortunately, almost all of the frescoes - they were only uncovered and renovated in 1955/56 - have been damaged by enlarged windows and beam supports: a testimony to the Reformation's rejection of Catholicism's cult of images.
There is a pretty tubular fountain from the 18th century in the village. The oldest part of the picturesque town hall dates back to a chapel of St George.
The first documented mention of Blansingen dates back to 1094, when parts of the village became the property of the monastery of St. Georgen in the Black Forest. In 1464, the village passed to the Margraves of Hachberg-Sausenberg.
