I WONDER - How Did The Vikings Keep Warm?

The video discusses the multifunctional role of fire in the Long house, providing light, heat, and a means to cook food. Ashes from the fire were used to absorb moisture on the floor. The roof had holes to allow smoke to escape, and the fire was kept burning constantly, especially in colder climates. Multiple families lived in the Long house, with those closer to the fire benefiting from its warmth.
