I wish I had touched this plant to test its structure and feel since it's used as roofing for the Teitos. It really must be strong.
This photo highlights the plant that is absolutely central to the identity of **Somiedo**: **Broom** (specifically *Cytisus scoparius* or *Genista*, known locally as **Escoba**). Its long, flexible, and extremely durable branches are bundled together to create a waterproof layer that can withstand the heavy Asturian snow.
Because it grows so densely and can be quite tall (as seen compared to your eye level in the photo), it was historically used by shepherds to create natural barriers for livestock.
