Townlands are small geographical divisions of land in Ireland, traditionally used for administrative purposes. They vary in size and can encompass a few acres to several hundred acres. Each townland has a unique name, often derived from the local landscape, history, or language. These divisions play a significant role in local identity and community. Townlands are often used in addressing mail and are important for land registration and mapping. They are also a key feature in Irish culture, reflecting the historical and social fabric of the region.
