Palacio de Cibeles (Cibeles Palace), Madrid (must see)

Located on one corner of Cibeles Square ("Plaza de Cibeles"), this remarkable structure was originally built as the headquarters of Spain's postal service. Designed by the by the prolific architect partnership of Antonio Palacios and Joaquín Otamendi, the building's white façade with its tall pinnacles has often been compared to a wedding cake. In 2011, a magnificent glass dome was added to the central courtyard, enhancing its grandeur.

By the main entrance, you can still spot the traditional brass letterboxes embedded in the wall, labeled with the names of different Spanish cities and provinces. Today, the building serves as the offices of the Mayor of Madrid and the City Council, while also housing CentroCentro, a vibrant cultural center offering a diverse range of workshops, exhibitions, and concerts that celebrate Madrid. The center features a lively lounge area by the entrance hall, overlooking Cibeles Square, providing a trendy spot to unwind. For breathtaking panoramic views of Madrid, head to the viewpoint/terrace on the top floor, which has become a popular gathering place, especially during the early evening.

During special occasions like Christmas, the building serves as a stunning backdrop for dazzling illuminations and projected images.
