Hacienda de Belén is located where the town of Bormujos likely originated. The buildings, in the vernacular Andalusian rural-style, now house the municipal services.
The estate still preserves part of the oil mill, wine press and cellar, which, together with the residential quarters, are distributed around a central courtyard. The other farm buildings are clustered around an irregularly shaped work yard.
There is a yellow-and-blue, eight-tile panel on the façade, probably from the 18th century, representing the mystery of the Holy Trinity.
