Kilian's Church on Kaiserstraße in Heilbronn is a Gothic hall church constructed from Heilbronner sandstone, whose origin dates back to the 11th century. Its western tower, constructed by Hans Schweiner, is one of the first major Renaissance buildings to be built north of the Alps. Inside the church there is an altar by Hans Seyffer from 1498, which is regarded as a masterpiece of sculpture from the Late German Gothic period. Some of the stained glass is by Charles Crodel. The Monument Foundation of Baden-Württemberg appointed the church as monument of the month in December 2016.
