Buelna is one of two lugares in Pendueles, the other one also named Pendueles.[2] It has suffered a population decrease, coming from 79 people in 2010 to 47 people in 2023. It is known for its beach, 600 m. away from the town and its traditional Asturian houses.[3]
The Church of Santa María de Buelna was home to the Count of Valle de Pendueles.[4]
The term Buelna can date back to 978, first found as, which then evolved to, then entered diphthongisation as or, and after became Buelna.[5] The terms may be from the Proto-Indo European root (water that shakes).[6]
