Clackmannan ( listen (help·info); Scottish Gaelic: Clach Mhanainn, perhaps meaning "Stone of Manau"), is a small town and civil parish set in the Central Lowlands of Scotland. Situated within the Forth Valley, Clackmannan is 1.8 miles (2.9 km) south-east of Alloa and 3.2 miles (5.1 km) south of Tillicoultry. The town is within the county of Clackmannanshire, of which it was formerly the county town, until Alloa overtook it in size and importance. According to a 2009 estimate the population of the settlement of Clackmannan is 3,348 residents.
The name of the town refers to the Stone of Manau or Stone of Mannan, a pre-Christian monument that can be seen in the town square beside the Tolbooth or Tollbooth Tower, which dates from 1592.
During the 12th century, the area formed part of the lands controlled by the abbots of Cambuskenneth. Later it became associated with the Bruce family, who, during the 14th century, built a strategic tower-house. It still stands above the town according to Historic Scotland, but entry is forbidden (because of subsidence).
A crater on asteroid 253 Mathilde is named after Clackmannan. Because Mathilde is a dark, carbonaceous body, its craters have been named after famous coalfields from across the world. The Clackmannan Group is the name given to a suite of rocks of late Dinantian and Namurian age laid down during the Carboniferous period in the Midland Valley of Scotland. The war memorial was designed by Sir Robert Lorimer in 1919.
