Tower houses are tall, narrow buildings that often feature multiple stories. They were commonly built in medieval times, particularly in regions like Scotland and Ireland. These structures served both residential and defensive purposes, allowing families to live comfortably while also protecting themselves from potential threats. Typically made of stone, tower houses have thick walls and small windows to enhance security. The layout usually includes a central hall and various rooms on different levels. Some tower houses are still standing today and are popular tourist attractions, showcasing the architectural style and history of their time.
