The Alvear Palace Hotel is a luxury hotel in Avenida Alvear in Recoleta, an upscale neighbourhood in Buenos Aires, Argentina.

The hotel was built by Buenos Aires businessman and socialite Dr. Rafael de Miero, who had been to Paris in the early 1920s and wanted to bring a comparably grand Belle Epoque hotel to his then-flourishing hometown.

He bought and demolished a large house on the corner of Avenida Alvear and Ayacucho in 1922, which began the decade-long on-again, off-again project, which finally opened in 1932.

A success, it was expanded in 1940, consuming another old mansion on Avenida Alvear.

[1] In 1970, ownership passed to the 26-year-old Andreas von Salm-Kyrburg Wernitz, Duke of Hornes, Spanish cousin of King Juan Carlos I,[2] who presided over the hotel's slow decline as a result of labour disputes and a general Argentinian economic stagnation.
