Blackhouses are traditional dwellings found primarily in the Scottish Highlands and Islands, particularly on the Isle of Lewis. They are characterized by their thatched roofs and stone walls, often built with local materials. The interiors typically feature a central hearth for cooking and heating, with living spaces arranged around it. These homes were designed to withstand harsh weather conditions and provide warmth. The name "blackhouse" comes from the soot that would accumulate from the fire used for cooking and heating. Today, many blackhouses have been preserved as historical sites, showcasing the unique architectural style of Scottish culture.
