Casa Salazar-Candal () is a historic building located on the southeast corner of Isabel and Mayor Cantera streets in Ponce, Puerto Rico, in the city's historic district. The building dates from 1911. It was designed by the architect Blas Silva. The architecture consists of 19th Classical revival, Art Nouveau and Spanish Revival architectural styles. Today the Salazar–Candal Residence houses the Museum of the History of Ponce. History Casa Salazar was designed in 1911 by Blas Silva Boucher as the residence of Dr. Guillermo Salazar Palau and his wife Sara Isabel Rivera Carbonell. The house was a Guillermo Salazar Palua's wedding gift to his wife Sara Isabel. Later, it became the headquarters of the Alianza Nacionalista de Ponce (Ponce Nationalist Alliance) and later on yet, the headquarters for the Liga Progresista de Ponce (Ponce Progressive League), an organization seeking to preserve and advance the social, cultural, and commercial interest of the city during the first half of the twentieth century. Significance Casa Salazar-Candal is one of a group of stylistically eclectic houses built in Ponce between 1900 and 1915. Designed by architect Blas C. Silva Bouscher in 1911, the building reflects an emerging tendency to incorporate freely diverse and competing architectural motifs. The facade is distinctly rendered in roccoco and moorish detailing to emphasize its bifunctional character as a home and an office respectively. The portion of the structure designed to shelter the family is refined, delicately ornamented and asymmetrical. It utilizes a balcony, raised and detached from the street as a transitional zone between the public and the private sphere. In contrast to the refinement and gentility of the house expressed by its fluted corinthian columns, floral surrounds and composite entablure, the office is fashioned as a moorish garrison exhibiting a crenelated parapet, horseshoe arches with simplified surrounds and planar surfaces. The building plane of the office is pushed forward to meet the sidewalk for public access in order to further express its utilitarian function. Master craftsman Elias Concepcion has been credited with the execution of the interior finishes. His handling of the ornamental elements ranges from the curvilinear and stylized floral motifs present in the stained glass of the double doors, to the rectilinear wood screen—reminiscent of the arts and craft movement – dividing the foyer from the living room. As with the exterior, the interior is a mixture of distinct stylistic elements. The vestibule's repousse sheet metal ornamentation
