Clackmannan is a town and civil parish embeded in the Central Lowlands of Scotland. Positioned within the Forth Valley, Clackmannan is 1.8 miles (2.9 km) south-east of Alloa and 3.2 miles (5.1 kilometres) south of Tillicoultry. The community is within the area of Clackmannanshire, of which it was previously the county town, until Alloa overtook it in dimension and also relevance. According to a 2009 estimate the population of the settlement of Clackmannan is 3,348 citizens. The name of the community describes the Stone of Manau or Stone of Mannan, a pre-Christian monolith that can be seen in the community square next to the Tolbooth or Tollbooth Tower, which dates from 1592. Throughout the 12th century, the area developed part of the lands regulated by the abbots of Cambuskenneth. Later it came to be associated with the Bruce household, that, throughout the 14th century, built a critical tower-house. It still stands over the town according to Historic Scotland, yet entry is restricted (because of subsidence). A crater on planet 253 Mathilde is named after Clackmannan. Since Mathilde is a dark, carbonaceous body, its craters have actually been called after popular coalfields from across the world. The Clackmannan Team 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 created by Sir Robert Lorimer in 1919.
