This Coat of arms is in a panel of information.
"The shield of Castrillón (Principality of Asturias) is divided into two parts and has the Royal crown of Spain on it:
The one on the left contains a Field of Azure, with a crenellated tower that represents the Castle of Gauzón on a green hill and above it the Victory Cross, with the letters of the Greek alphabet alpha and omega.
The one on the right contains a Field of Gules and a golden warship that crosses the sea to break the chain that connects two towers. It was taken from the shield of Avilés when Castrillón was incorporated, as well as several other councils took it. Represents the conquest of Seville, which they went to help recover"
