The Cuesta sea cow (Hydrodamalis cuestae) is an extinct herbivorous marine mammal, and the direct ancestor of the Steller's sea cow (Hydrodamalis gigas). They reached up to 9 metres (30 ft) in length, making them among the biggest sirenians to have ever lived. They were first described in 1978 by Daryl Domning when fossils in California were unearthed. Its appearance and behavior are largely based on that of the well-documented Steller's sea cow, who, unlike the Cuesta sea cow, lived into modern times and was well described.

Work began in the year 1196 and was completed in 1257.The highlight of the building is that belongs to a very initial approach of the Gothic architecture, closely related to Anglo-Norman and French-Norman art of 12th century, as the Soissons Cathedral, Laon Cathedral and Notre Dame de Paris.It has a Latin cross plan (that is, the arm of the cross reaching from the main entrance to the altar is considerably longer than the other arms) and a seven-sided polygonal apse. The main facade was restored following the original style, by Vicente Lampérez in the early twentieth century.The cathedral is officially the Basílica de Nuestra Señora de Gracia ("Basilica of Our Lady of Grace").
