This door was also known as the Royal Door because of the weapons that decorated it. The coats of arms could be seen from the Campo da Feira and were located above the door according to the description: on the left the one of the Kingdom of Galicia with 5 ciboria or chalices; in the centre of the one of Castile and Leon and on the right the one of the city with the bridge and the tower. Under them there is an inscription LAS: DEL: REI: NO: E: LA CIBDAD. They would have been dated to the last third of the 15th century, after the granting of the title of city to Betanzos by Henry IV in 1465. Curiously, they were replaced once the reconstruction of the gates and walls ordered by the Catholic Monarchs was carried out. Furthermore, the royal coat of arms does not contain any reference to Granada, which means that they predate the capture of the Nasrid city in 1492.
Did you know that the Galician coat of arms on this door is the oldest representation of this emblem that is preserved in the whole region? With its five ciboriums, it symbolises the five provinces into which the Kingdom of Galicia was divided until the 15th century, later becoming seven, until the current division into four.
In 1865 the Town Hall of Betanzos decided to break down the doors because they made it difficult for people to enter. Throughout that year, this door was demolished but the coats of arms were preserved, placing them on the houses that existed there. It was not until 1903 that an extension and widening project was carried out, which would be completed in 1911 with the Modernist railings and street lamps.
