Construction work began in 1909 and lasted quite a long time. The best specialists of the time were involved in the project: architects Joaquín Otamendi and Antonio Palacios. The works were supervised by the experienced engineer Ángel Sainz Chueca. The construction lasted 12 years. The total cost of the building amounted to twelve million pesetas, which was almost three times the originally proposed budget. Representatives of the Spanish royal dynasty attended the grand opening in the spring of 1919. The project was so successful that the entire creative team immediately became in high demand.
Originally, the building was intended to be used as a Palace of Telecommunications. At the beginning of the 20th century, postal and telegraph services were experiencing a period of rapid development. Telephone communication was considered incredibly progressive, almost fantastic. The Spanish government endeavored to use all innovations in this area and actively develop it. Over time, the building housed the head office of the Universal Postal Union. It became a hub for all information related to new technologies in the field of communications.
Throughout its history, the building was very actively used. At the same time, it served as a decoration for the city and a real pride for the people of Madrid.
In 1993, the Palacio de Cibeles was officially granted the status of a cultural heritage site. Since then, numerous transformations have begun in the palace. The building became multifunctional. It concentrated a large number of venues for cultural city-wide events. In addition, the Cibeles houses the city administration offices. Since 2007, the city hall has been located on the premises of the palace.
The complex covers an area exceeding 12,000 square meters. It is divided into multiple sections, each bearing a specific functional purpose.
The building was constructed in a unique Neo-Churrigueresque style, characterized by architectural eclecticism. Intricate forms are present on the facade walls, especially abundant at the top level and above the window openings. The combination of columns and pinnacles helps to create a cohesive image. The upper level is crowned with patterned turrets of varying heights. Inside, the building features many glass and plastic panels, as well as numerous chrome elements, giving it a modern and business-like appearance. The design successfully combines various stylistic techniques: Baroque stucco work and high-tech elements. A semi-transparent section with stained glass is arranged in the center of the roof, allowing sunlight to freely penetrate from above. Even the flooring appears to be made of crystal. The silver tiles also absorb and reflect daylight.
Inside, there are many relaxation zones with soft sofas and expensive plants in elegant planters. The advantageous location of the Sibelius has facilitated the presence of: many municipal offices; exhibition halls and galleries; souvenir shops; youth cafes; a reading room; and a luxury restaurant.
The palace leads a very vibrant life. In the exhibition halls, one can always admire the fashionable exhibitions of the season, which never repeat.
The surrounding beauty is more fully revealed from the observation deck on the roof of the palace, offering delightful views of Madrid.
