The ruins of Langheim Abbey, a Cistercian monastery founded in 1132, lie in the village of Klosterlangheim about 5 km east of Lichtenfels. The monastery was once one of the wealthiest and most influential in Franconia, with a church larger than many cathedrals. Secularised in 1803, it was subsequently dismantled and the stone reused for local building projects; today only the gatehouse and some walls survive.
A heritage trail through the village maps the former extent of the monastery complex. The remaining gatehouse is in good condition and gives a sense of the scale and quality of the original building. The site is peaceful and visited by few tourists — those who make the effort tend to be interested in Cistercian history or medieval architecture. It pairs well with a visit to Banz Abbey, which suffered a similar fate but has been better preserved.
