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 community is within the region of Clackmannanshire, of which it was previously the county town, till Alloa overtook it in dimension as well as value. According to a 2009 estimate the population of the settlement of Clackmannan is 3,348 homeowners. 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 close to the Tolbooth or Tollbooth Tower, which dates from 1592. Throughout the 12th century, the location created part of the lands managed by the abbots of Cambuskenneth. Later it came to be connected with the Bruce household, who, throughout the 14th century, built a critical tower-house. It still stands over the town according to Historic Scotland, but entrance is prohibited (because of decrease). A crater on asteroid 253 Mathilde is named after Clackmannan. Due to the fact that Mathilde is a dark, carbonaceous body, its craters have actually been named after well-known coalfields from throughout the world. The Clackmannan Team is the name offered to a collection of rocks of late Dinantian and also Namurian age put down throughout the Carboniferous period in the Midland Valley of Scotland. The war memorial was designed by Sir Robert Lorimer in 1919.
