A hjallur is a traditional Icelandic structure used primarily for storing hay and other agricultural products. These buildings are typically made of wood and feature a slanted roof, which helps to shed snow and rain. The design allows for good ventilation, keeping the stored materials dry and preventing spoilage. In rural Iceland, hjallur structures are often found on farms, reflecting the country’s agricultural heritage. They are an important part of Icelandic culture, showcasing the practical solutions developed by farmers to cope with the harsh climate and ensure the preservation of their resources.
