Balsera Palace, Art Nouveau palace in Avilés, Spain.

Balsera Palace is a building in Avilés whose design sits between modernism and eclecticism, with a curved corner leading up to a slender historicist tower. It was built by architect Antonio Palacios for merchant Victoriano Fernández Balsera. Inside, a V-shaped staircase opens toward the first floor, and the flat roof and tower balcony look over the historic city.

Antonio Palacios, an architect from Pontevedra, designed the palace for the Avilés merchant Victoriano Fernández Balsera; sources date it to 1909 or possibly 1917. The city bought the building in 1982 and renovated the interior in 1984 and 1997, keeping its original layout. The façades were restored between 2011 and 2012, and it was declared a monument on 3 October 1991.

The building now serves as the Julián Orbón Municipal Conservatory of Music, where students study orchestral instruments and piano in its refined spaces. This use connects the palace to the city's cultural life through daily musical practice and performance.

The exterior underwent restoration work from 2011 to 2012 to repair damage from weather, including facade cleaning and interior repainting. The building now operates as a public cultural space, so visitor access may vary depending on events and activities taking place inside.

The original property featured extensive grounds comparable in scale to Versailles, though only a portion remains visible near the structure today. This reveals how grand and influential the original estate once was on the city landscape.
