El Castillo Hotel is a building with medieval-style architecture that was built in 1870[citation needed] and is located in Valle Hermoso (Córdoba), Argentina.

The farmhouse was expanded in the early 20th century, while conserving its medieval Florentine style, and turned into the luxurious "Hotel Monte Olivo", refitted with granite and parquet flooring, cedar and cinchona cabinetry, Provence furniture, porcelain and silver tableware, bronze bathroom fittings, and wrought iron light fixtures.

From 1970 to 2000, the property was used as a summer camp for the metal workers union ("Unión Obrera Metalúrgica"), and was allotted to student and senior tourism operators.

In the different modules, the building combines materials such as stone, brick, fine plaster, solid wood, and wrought iron.

The analysis shows special emphasis on the high risk that the entrepreneurial family had to overcome, with obstacles such as the profound economic crisis (the December 2001 Crisis in Argentina), lack of credit, remote vendors, expensive technology, changing context, devalued location, and laws contrary to ecotourism.
