The residence of the Arzobispo Nouel #5, corner of Hostos, was originally a sixteenth-century building. The original house had a single level. It was subsequently modified the point of preserving small traces of its original structure. ￼Door openings and windows were walled up in the ancient colonial house, as well as its main doorway facing the calle Hostos. New doors on both sides were opened to give the property a commercial use.
A second level was added to the residence, using reinforced concrete, featuring an open-courtyard Spanish terrace. A new facade was superimposed of the same material with neoclassical details. Also, splendid floor tiles and a stunning concrete staircase with a mahogany veranda were added. The house had been known during the 1920s as Casa 21 of calle Hostos. Throughout most of the 19th century it belonged to the De la Concha family. ￼The brothers Jacinto, Tomás and Wenceslao de la Concha were all well-known patriotic activists who advocated heroically, with Juan Pablo Duarte, Francisco del Rosario Sánchez and Matías Ramón Mella, for the National Independence. ￼In the home of the de la Concha brothers, political meetings were held and many patriots fleeing persecution sought refuge. During a meeting it was agreed that the 27th of February should be the night in which the Free and independent State of the Dominican nation was to be proclaimed. The house was owned by General Wenceslao Figuereo, whom became vice-president of in the late nineteenth century, alongside President Ulysses Heureaux. When the latter is deposed by complot, Figuereo became president for a short term. Also at this residence, the Dominican Party was founded by dictator Rafael Leonidas Trujillo. Then in the last two years it served as commercial space on the first level, and apartments and offices on the second floor.
