Puerta de Alcalá is the former eastern gate of the city erected in the classical style. Located on the Independence Square (Plaza de la Independencia) in Madrid. It was made of granite, the author of the design was Francesco Sabatini. Noteworthy are the limestone sculptures by Francis Gutierrez (including allegories of the four cardinal virtues) and the Frenchman Robert Michel (shields of the western facade).
The road from Alcalá de Henares once led through the eastern gate to Madrid, hence the name of today's monument. The gate was built in the second half of the 18th century - the time of construction is commemorated by a plate made of stone, which was placed in the center of the monument.
It is believed that allegorical sculptures were supposed to praise the virtues of King Charles III - his prudence, justice, perseverance and moderation. They are represented here by the characters of young children, a characteristic motif for the Baroque style.
