Clackmannan is a town as well as 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 also 3.2 miles (5.1 kilometres) south of Tillicoultry. The town is within the area of Clackmannanshire, of which it was previously the county town, until Alloa surpassed it in size and value. According to a 2009 quote the population of the settlement of Clackmannan is 3,348 residents. The name of the community describes 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. Throughout the 12th century, the location formed part of the lands regulated by the abbots of Cambuskenneth. Later it came to be related to the Bruce family members, who, throughout the 14th century, developed a strategic tower-house. It still stands above the town according to Historic Scotland, yet entry is forbidden (due to subsidence). A crater on planet 253 Mathilde is named after Clackmannan. Due to the fact that Mathilde is a dark, carbonaceous body, its craters have been called after popular coalfields from across the globe. The Clackmannan Team is the name offered to a collection of rocks of late Dinantian and Namurian age put down during the Carboniferous duration in the Midland Valley of Scotland. The war memorial was created by Sir Robert Lorimer in 1919.
