El Hospitalón, Pola de Lena Monument · Lena, Caudal, Asturias Image of Lena, not of the place itself. A large 16th-century building in the Lena capital, remodelled many times over its history. From the original fabric it still preserves a window with carved decoration and an arch with a dripstone, both uncommon in the civil architecture of the valley.
