When Madrid became the capital of the Spanish Kingdom, architect Gomez de la Mora was given the task of designing a building that will fit the needs of the municipality, and will show the standing of the new capital.
In the second half of the 18th century a balcony was added to the building, where from the kings of Spain watched religious parades. As well as bein g the City Hall building, the building was also used as a prison. This is when separate entrances were planned for the building, for the different uses.
At the start of the 20th century, when the building became too small for the management of the city activities in Madrid, the municipality bought the Casa de Cisneros next door. Activities were expanded into the additional building. This palace look-alike, built in the 17th century, was planned in the Plateresco style, also called Spanish Renaissance style, a Spanish spin-off of the Italian Renaissance style.
