Castillo Marroquín, Châteauesque house in Chía, Colombia.

Castillo Marroquín is a châteauesque mansion in the countryside of Chía, built across expansive grounds with two main floors and towers reaching four stories high. The structure commands views over the surrounding Cundinamarca region and the Andean landscape beyond.

Lorenzo Marroquín Osorio commissioned this châteauesque palace in 1898 from French architect Gaston Lelarge, with master builders Julián Lombana and Demetrio Chávez, on 61 hectares of the Hacienda El Castillo at La Caro. After the Marroquín family sold it, it stood abandoned, then served as a cabaret and a women's psychiatric hospital. Surgeon and writer Roberto Restrepo restored it after buying it in 1952; oilman Guillermo Villasmil added a pool and guest rooms in 1970. Seized from the Zapata family by Spanish justice in March 2005 over Medellín Cartel links, it was restored by architect Francisco Restrepo and rented as a Bogotá events centre.

The name comes from the Marroquín family: Lorenzo Marroquín Osorio, son of former president José Manuel Marroquín, commissioned it on the grounds of the Hacienda El Castillo. Before becoming an events venue it housed a cabaret and later a women's psychiatric hospital. Today it is rented out for conventions and celebrations in the La Caro sector of Chía.

The castle stands on the grounds of Hacienda El Castillo in the La Caro sector, on the road between Bogotá and Chía, in the municipality of Chía, Cundinamarca. It is rented out as an events and conventions centre, so it is normally seen by attending a booked event rather than on a walk-in visit; arrange access through the venue beforehand.

The castle's later history is often left out: it was rented as a cabaret, then as a psychiatric hospital for women, and at one point belonged to a mafia figure. In March 2005 the Spanish courts seized it from the Zapata family over links to the Medellín Cartel.
