Clackmannan is a small town and civil parish set in the Central Lowlands of Scotland. Positioned within the Forth Valley, Clackmannan is 1.8 miles (2.9 kilometres) south-east of Alloa and also 3.2 miles (5.1 kilometres) south of Tillicoultry. The community is within the county of Clackmannanshire, of which it was previously the county town, till Alloa surpassed it in dimension and significance. According to a 2009 quote the population of the settlement of Clackmannan is 3,348 locals. The name of the community refers to the Stone of Manau or Stone of Mannan, a pre-Christian monument that can be seen in the town square next to the Tolbooth or Tollbooth Tower, which dates from 1592. Throughout the 12th century, the area developed part of the lands controlled by the abbots of Cambuskenneth. Later it ended up being associated with the Bruce family, that, throughout the 14th century, developed a critical tower-house. It still stands above the town according to Historic Scotland, yet entry is prohibited (because of subsidence). A crater on planet 253 Mathilde is named after Clackmannan. Because Mathilde is a dark, carbonaceous body, its craters have actually been called after famous coalfields from across the world. The Clackmannan Team is the name offered to a collection of rocks of late Dinantian and also Namurian age put down during the Carboniferous period in the Midland Valley of Scotland. The war memorial was designed by Sir Robert Lorimer in 1919.
