Lignol lies in the valley of the river Scorff. The village centre is located 16 km (9.9 mi) east of Le Faouët, 22 km (14 mi) west of Pontivy and 33 km (21 mi) north of Lorient. Historically, it belongs to Vannetais.

There is a church in this town that was built during the 14th century. Lignol also has two castles, they were the homes of the dukes that used to rule the place and were under the domination of the House of Rohan. Lignol was the main place of the French resistance against the German occupation in the Guémené-sur-Scorff area. Since the Nazis occupied Guémené-sur-Scorff, the Resistance used the nearby towns as bases. Langoëlan and Lignol were their main ones in the region.

Agriculture is the main source of resources of the town.

During the presidential 2007 elections, inhabitants voted for Nicolas Sarkozy. Its current mayor is a former farmworker.

Lignol has a soccer club in association with the neighbouring town of Kernaskleden.
