1911 Encyclopædia Britannica/Morón de la Frontera
MORÓN DE LA FRONTERA, or Morón (anc. Arumi), a town of southern Spain, in the province of Seville; 32 m. S.E. of the city of Seville. Pop. (1900) 14,190. Morón occupies an irregular site upon broken chalk hillocks near the right bank of the Guadaira. It is connected by rail with Utrera on the Cadiz & Seville line. On the highest elevation to the eastward are the ruins of the ancient castle, of considerable importance during the Moorish period, when Morón, as its full name implies, was a frontier fortress; the castle was afterwards used as a palace by the counts of Urena. In 1810–1811 it was fortified by the French, but blown up by them in the following year. The chief public building of Morón is the large parish church, which dates from the 16th century. Morón is also famous throughout Spain for its marble and its chalk (cal de Morón), from which the whitewash extensively used in the Peninsula is derived.
